The Bordo 2.5 x 0.45 mm MC Bottoming HSS Tap is part of Bordo’s professional HSS hand and machine tap range, engineered to deliver dependable metric coarse thread cutting performance in both workshop and on-site applications. Designed to produce full-form threads right to the bottom of blind holes, this bottoming tap is ideal for finishing threads after pilot hole preparation.
Manufactured from premium High Speed Steel (HSS), this metric coarse (MC) bottoming tap features a 60° thread angle with a flat crest and clearance at the root, allowing strong engagement between internal and external threads and enhancing thread strength. Bottoming taps have a short lead of two threads before full threading — ensuring minimal thread run-out when tapping to the bottom of blind holes. Typically used after a taper or intermediate tap, this tool is suited for use with both hand and general machine tapping operations in medium tensile materials.
Bordo is recognised for producing dependable threading and cutting tools manufactured to consistent industrial standards — and Industrial Shed ensures fast access to these trusted trade-grade taps when you need them on site or in the workshop.
