6 Packs M6 Combination Drill & Taps Bit Set, Screw Threading Tapping Tools in Size M6*1.0 with Anti-Rust Black Coating, 1/4" Hex Shank and Storage Case

Combine drill and tap in a single step - this all-in-one tool works great and saves considerable time and effort when creating threads for hinges or other projects; no more drilling a hole first and then tapping it out later with a separate tool. HIGH VERSATILITY Set of 6 drill tap bits in sizes M6* 1.0, with 1/4" hex quick-change shank, fits electric hand drill, impact drill, bench drill, electric screwdriver and other tap machines. HANDY TOOLS These drill-tap bits are a must-have if you fabricate a lot; you can use them in aluminum, plastic, wood and other thin soft material metal panels.

When using, make sure the bit is perfectly straight, take your time, go slow, and use lubrication to prevent breaking the bit in the hole. EASY TO USE Each tap drill is engraved with its size, convenient for you to choose the suitable size at a glance. A tapered end on the hex shank can prevent excessive knocks; back taper exceeds the tap to prevent over-drilling and damage to the thread. This drill tap bits set comes with a portable storage case for convenient use and storage
