Wide Recess Cutting for Trays, Bowls & Boxes

Carbitool dish cut bits are purpose-built for woodworking jobs where material needs to come out of the face of the workpiece rather than simply off its edge. With wide cutting surfaces, rounded internal corner radii & both bearing-guided & non-bearing configurations, the range is suited to routing trays, bowls, plates, boxes & similar recessed forms.

Where a project needs a narrower rounded groove instead of a broad recessed area, Carbitool Core Box Bits provides a distinctly different cutting geometry. Buyers planning other routing operations around the same project can explore Carbitool Router Bits for the wider Carbitool cutter range.

Four cutters make up the current collection, but their differences matter. Diameter determines how much surface the cutter covers, radius influences the transition between the floor & wall of the recess, while the bearing changes how the tool can reference the work.

What Are Carbitool Dish Cut Bits?

Dish cut bits are broad router cutters designed to remove material across recessed areas in timber projects.

Carbitool describes this cutter family specifically for routing trays, bowls, plates & boxes. Its wide surface cut is intended to remove excess material quickly compared with relying on a much narrower profile cutter for the same type of work.

Unlike a straight bit that leaves a sharper internal transition, the Dish Cut family incorporates a defined corner radius.

That creates an important visual & practical distinction in the recess: a broad floor transitions into the surrounding wall through a radius rather than a square internal corner.

Carbitool divides the range into two configurations:

• Two-flute dish cut bits without bearings

• Two-flute dish cut bits with bearing guides

All four current options are carbide tipped with 1/2" / 12.7mm shanks.

Why Choose Carbitool Dish Cut Bits?

Picture the bottom of a serving tray.

The main area needs material removed efficiently, yet the perimeter transition also contributes to the finished shape. A narrow decorative bit would make the clearing process unnecessarily inefficient, while a conventional straight cutter would create different internal geometry.

Dish cutters address both parts of that problem through a wide cutting surface + rounded corner radius.

Four Cutters, Three Working Diameters

Industrial Shed's current range covers:

Those measurements show why “dish cutter” alone is not enough information for selection.

The 19mm cutters share a 4.75mm radius, but one adds bearing guidance.

Moving to 28.6mm or 32mm changes both the working width & corner geometry.

Carbide-Tipped, Two-Flute Construction

Carbitool classifies every current Dish Cut model as a two-flute, carbide-tipped router bit.

That wording is worth retaining accurately.

These are not generic “solid carbide or TCT” products, despite the broad description currently repeated across Industrial Shed's product cards.

Bearing-Guided Options Change the Routing Method

Adding a bearing does more than create another SKU.

A bearing provides a physical reference that can follow a suitable template or edge arrangement in an appropriate routing setup.

That can be useful when the recess shape needs to follow a defined boundary.

The non-bearing cutters remain relevant where guidance comes from another controlled routing method.

Common Applications

Serving Trays

A tray recess needs both an open central area & a controlled perimeter.

Dish cutters are particularly well aligned with this task because Carbitool explicitly identifies trays as an intended application.

Cutter diameter affects clearing width, while radius determines the transition left at the edge of the routed area.

For repeat tray designs, a controlled template or routing system can help maintain the same footprint between pieces.

Routed Bowls & Plates

Shallow bowl or plate forms introduce the same fundamental requirement on a different scale: remove material across an area while retaining a rounded transition around the recess.

Do not interpret the word “bowl” as meaning the cutter automatically creates an entire finished bowl profile.

The bit machines according to its cutter geometry, depth & routing path. The overall form still depends on the project design & setup.

Timber Boxes With Recessed Interiors

Small boxes, organisers & timber storage pieces can require a machined cavity rather than an assembled internal compartment.

A dish cutter provides one method of clearing that area.

The available 19mm, 28.6mm & 32mm diameters allow the routing strategy to be matched more closely to the scale of the recess.

Repeated Recesses From a Template

What happens when ten components need the same cavity rather than one?

Repeatability becomes as important as the first finished recess.

Bearing-guided TD 706 B 1/2 & TD 712 B 1/2 cutters introduce a physical guide into the setup, making them particularly relevant when the intended routing method uses a compatible template or reference.

Template security matters throughout that operation. Clamps & Vises provides a broader workholding category for appropriate workshop setups.

Furniture & Joinery Features

Recesses do not have to become trays or bowls.

A furniture component can incorporate a routed pocket or dish-shaped feature as part of its functional or visual design.

What matters is whether the cutter's diameter, radius, available cutting dimension & routing method correspond with the intended form.

Product Selection Guide

With only four cutters, selection should be straightforward once the recess itself is understood.

Start With the Corner, Not Just the Diameter

What should happen where the floor of the recess meets its wall?

That transition is one of the defining features of this cutter family.

The 19mm models use a 4.75mm radius.

The 28.6mm bearing-guided cutter uses a 6mm radius.

The 32mm non-bearing cutter increases to 6.5mm.

If an existing tray, box or routed component is being reproduced, compare that radius as well as the overall cutting width.

19mm or a Wider Cutter?

A 19mm cutter covers less surface on each routing path than the wider alternatives.

The 28.6mm & 32mm models offer broader cutting widths.

That does not automatically make the largest cutter the correct choice.

Internal dimensions, corner access, desired radius, router compatibility & the routing strategy all contribute to the decision.

Bearing or Non-Bearing?

This choice is fundamentally about how the cutter will be guided.

A bearing-guided model can follow a suitable physical reference.

A non-bearing cutter requires the routing path to be controlled by another appropriate method.

Decide how the recess will be produced before deciding whether the bearing is useful.

Compare the Two 19mm Options

TD 706 1/2 & TD 706 B 1/2 share a 19mm cutter diameter, 19mm cutting dimension & 4.75mm radius.

The major functional difference is guidance.

TD 706 B 1/2 adds the bearing assembly, increasing overall length from 64mm on TD 706 1/2 to 76.8mm.

For buyers who already know 19mm is the required geometry, the routing method can therefore settle the choice.

The 28.6mm Bearing Cutter Has Its Own Bearing Specification

TD 712 B 1/2 uses a TB18 bearing.

By comparison, TD 706 B 1/2 uses TB4.

Replacement bearings should be matched to the specific cutter rather than treating the bearing-guided Dish Cut family as one interchangeable assembly.

Every Current Option Requires a 1/2" Shank Setup

There is no 1/4" shank version in the current four-product Industrial Shed collection.

All use 12.7mm / 1/2" shanks.

Machine compatibility therefore needs to be established before ordering.

For Carbitool machine-interface components, Carbitool Collets provides a useful adjacent reference, although the exact router & cutter combination still needs to be verified independently.

Expert Tips

Map the Recess Before Removing Material

A broad cutter can remove material efficiently, which makes a routing plan more—not less—important.

Mark the intended boundary.

Establish the finished depth.

Understand where the corner radius will sit.

Then determine how the router will be controlled through the interior.

The cutter should execute the shape rather than define it by accident.

Avoid Treating Maximum Cutter Dimension as Target Depth

Catalogue dimensions describe the cutter.

They do not instruct the operator to plunge automatically to the maximum available cutting dimension.

Actual routing depth should follow the project, workpiece, router setup & appropriate machining method.

For repeat work where a physical depth reference is useful, Carbitool Gauges includes Carbitool's RDG-1 router depth gauge.

Clear a Large Recess as a Process

A 32mm cutter does not turn a large cavity into a one-pass operation.

The amount of material, recess depth, timber, router setup & cutter engagement all influence how the work should proceed.

Plan the removal sequence around controlled routing rather than forcing the finished depth or entire cavity into an unnecessarily aggressive cut.

Give a Bearing a Proper Reference

Bearing guidance only works as well as the surface it follows.

A template or reference with damage, debris or movement can transfer that irregularity into the routing path.

Inspect the guide before starting & make sure the setup remains secure throughout the operation.

Test the Radius Where Appearance Matters

The difference between a 4.75mm, 6mm & 6.5mm radius may sound small on paper.

Inside a shallow tray or finely detailed box, the visual difference can be noticeable.

A test recess in suitable offcut material can reveal whether the transition suits the design before the finished component is machined.

Leave Abrasive Finishing to Do Finishing Work

Sanding may form part of the final surface preparation, but it should not be expected to transform the wrong cutter geometry into the right one.

Establish the required radius & recess form with the appropriate tooling first.

Where curved or internal surfaces require controlled abrasive work afterwards, Carbitool Sanding Sleeves provides replacement sleeves for Carbitool's DSK25 drum system.

When the Surface Changes, Diagnose Before Reworking the Design

A cutter that previously produced an acceptable result but now leaves a noticeably different surface deserves inspection.

Look at cutting-edge condition, accumulated residue, router setup, workpiece stability & the guidance system before changing dimensions or redesigning the recess.
