Not all drill bits have a clean shank. Whereas all of them have a round cross-section, a few of them have a threaded shank. Generally known as threaded shank drill bits, they’re used to create holes in objects and supplies. Threaded shank drill bits, nevertheless, function a novel design that makes them notably standard for aerospace-related functions.
What Are Threaded Shank Drill Bits?
Threaded shank drill bits are precisely what they sound like: drill bits with a threaded shank. Drill bits encompass a number of components. The highest half has the cross-section that, when pressed towards an object or materials, will create a gap because it spins.
Beneath the cross-section is the shank. The shank is the a part of a drill bit that connects to the drill. Whereas some drill bits have a clean shank, others have a threaded shank (see picture above).
Benefits of Threaded Shank Drill Bits
Why must you select a threaded drill bit over a conventional bit with a clean shank? With their means to screw into drills, they permit for larger precision when drilling holes.
Conventional drill bits are sometimes related to drills through a chuck. You loosen or open the chuck, place the bit inside, after which tighten or shut the chuck. Threaded shank drill bits, alternatively, are screwed into drills. They’re designed to be used with specialty drills that function threading fairly than a chuck. By screwing a threaded shank drill bit right into a drill, you’ll be able to relaxation assured realizing that it’s going to drill straight into objects and supplies.
Threaded shank drill bits are much less more likely to wobble than conventional bits. Wobbling happens when a drill bit sways to the facet. Threaded shank drill bits forestall wobbling to make sure straight and even holes.
You possibly can simply swap out threaded shank drill bits. Simply flip them counterclockwise to launch them from the drill. To put in a brand new threaded bit, flip it clockwise into the drill’s threaded bit holder.
Frequent Options of Threaded Shank Drill Bits
All threaded shank drill bits have exterior threading. That is primarily what distinguishes them from conventional drill bits with a clean shank. The outside threading permits them to connect with specialised drills.
As a result of they’re utilized in high-torque functions, comparable to automotive and aerospace drilling, threaded shank drill bits are robust. They’re product of sturdy supplies that may face up to excessive bodily stress, comparable to high-speed metal (HSS) and cobalt.
