Neprift KYY002 M6 x 1 Tap and 5.0mm Drill Bit Set, 2 pcs

Matched M6 x 1 Tap and 5.0mm Drill Bit Set

This set pairs an M6 x 1 spiral point tap with a 5.0mm twist drill bit, delivering a ready-to-use combination for creating machine screw threads. It suits professional machinists, automotive technicians, and serious DIY enthusiasts working on alloy steel, iron, and general metal fabrication or repair tasks.

HSS 6542 Tap and M35 Cobalt Drill Bit Construction

The tap is crafted from HSS 6542 high-speed steel for sharp, durable cutting edges, while the drill bit uses M35 cobalt steel that retains hardness at high temperatures. The spiral point tap design pushes chips forward during through-hole threading, reducing clogging and breakage risk during daily workshop use.

Through-Hole Threading Limitation

The spiral point tap is optimised for through-hole applications and is not suited for blind-hole threading where chips cannot escape forward. The 5.0mm drill bit size is fixed for M6 x 1 threads only, so the set cannot accommodate other thread pitches or diameters without additional tooling.
