Combine drill and tap in one step All-in-one design 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 SAE sizes, 10-32NC, with 1/4-inch 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 often; they can be used on aluminum, plastic, wood, and other thin soft material metal panels; when using them, ensure the bit is perfectly straight, take your time, go slow, and apply lubrication to prevent breaking the bit in the hole.

Easy to Use Each tap drill is engraved with its size for quick selection at a glance. A tapered end on the hex shank helps prevent excessive knocks; back taper exceeds the tap to prevent over-drilling and damage to the thread. This drill tap bits set includes a portable storage case for convenient use and storage
