20-Piece in handy case. We've examined every one to be sure it's full and sealed in a plastic bag. Some of these bits are as small around as splinters!
Brad point bits are used in non-metal applications only. Perfect for wood! The center point of the drill will make the bit track much straighter through wood than any other kind of bit. These bits are also to easier to get nice exit hole with less tear out. It's even possible to drill holes with part of the bit off the edge of the wood. Brad points are a secret of real craftsmen!
Great for deburring the inside of cut off brass/aluminum tubes. Use to relieve the edge of drilled & threaded holes. 82 degree cut.
Important Tip: The area right around the edge of a threaded hole can "ant hill" upwards when a fastener is tightened. This "ant hill" can mean only the very edges of the hole are pressed against the the bottom of the bolt head (or motor lug) and are in contact with the surface. Champfering the edges of the hole a little means the contact patch is moved outward from the hole edge making for more actual contact area. Any ant-hilling occurs inside the chamfer where it cannot interfere. Carbon steel. 1/2", 5/8" and 3/4".
118 degree point, high speed steel for drilling steel, wood and aluminum.

RC Drill Bits and Bit Sets
Model building calls for a lot of small, precise holes, and this category gathers the drill bits and sets that cover the tiny sizes hobby work demands. From sub-millimeter micro bits to number and letter sizing, the range reaches well below what a hardware-store set usually offers.
Micro and Metric Sets
The micro metric drill set spans 0.3 to 1mm, a small metric set picks up from 1.05 to 2mm, and a 20-piece micro bit set covers 0.03 to 1.6mm. These fine sizes suit drilling brass, hinge holes, and pin fits.
Number, SAE, and Brad Point Bits
Replacement number wire-size drill bits restore a gap in an existing set, a four-piece mini SAE set covers common fractional sizes, and an eight-piece brad point set drills clean, centered holes in wood. A sharp bit sized right for the job also keeps thin brass and hardwood from tearing at the edges of the hole.
