Coated Precision for Clean, Burr-Free Finishes

When you need fast, chatter-free countersinking, Sutton Tools delivers. These Coated Countersinks are made for machinists who demand smooth finishes & long tool life. Crafted from HSS-Co (Cobalt High-Speed Steel) with TiN & TiAlN coatings, they cut cleaner, last longer & resist heat under heavy use.

From structural steel to stainless & alloy plate, these countersinks remove burrs & create perfect seating for fasteners. Many trades pair them with Drill Accessories for accurate hole prep or use Cutting & Grinding Tools to fine-tune surfaces before final assembly. For workshop setups, Tap & Die Sets & Measuring & Inspection Tools keep your holes aligned & consistent to spec.

Industrial Shed stocks the complete Sutton range with Same-Day Dispatch across Australia, keeping production lines & job sites running without downtime.
