About Countersinks
Countersinks cut a cone-shaped opening to install screws and rivets flush with a surface or hold workpieces between centers on a lathe. They can also be used for chamfering and deburring.

Drill Bits
These jobbers'-length bits have the rigidity and length required for most applications.
Black-oxide and black-and-gold-oxide drill bits produce less friction than uncoated drill bits.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated and oxide-coated drill bits.
Drill bits with a split point keep centered without a pilot hole.

Drill Bits for Aluminum, Brass, and Bronze
Because softer metal, like aluminum, brass, and bronze, can clog a bit, the flutes on these bits lift chips out of the hole. Also known as slow-spiral drill bits. They are jobbers' length and have the rigidity and length required for most applications.

High-Speed Steel Drill-Bit Countersinks for Screws
For use on wood, plastic, and most metals, these countersinks attach to a drill bit (sold separately) to countersink and drill holes at the same time. They attach to the drill bit with two set screws and the position can be adjusted for different screw lengths. An 82° countersink angle is compatible with the profile of flat- and oval-head inch screws; a 90° countersink angle is compatible with the profile of flat- and oval-head metric screws and is also good for deburring.
Optional collar (not included) controls the cutting depth of your countersink. It attaches with two set screws.

Hardened Undersized High-Speed M2 Tool Steel Rods
- Yield Strength: Not Rated
- Hardness: Rockwell C60 (Very Hard)
These rods, also known as drill blanks, have an undersized diameter for machining your own jobbers'-length drill bits. They're hardened for increased abrasion and impact resistance. M2 tool steel offers a nice balance of wear resistance and machinability. It has a high molybdenum content, which allows it to maintain sharp cutting edges even at elevated temperatures.

Hardened Oversized High-Speed M2 Tool Steel Rods
- Yield Strength: Not Rated
- Hardness: Rockwell C60 (Very Hard)
Also known as reamer blanks, these rods have an oversized diameter that allows for finishing to your exact requirements. They're hardened for increased abrasion and impact resistance. M2 tool steel offers a nice balance of wear resistance and machinability. It has a high molybdenum content, which allows it to maintain sharp cutting edges even at elevated temperatures.
