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.

Center-Groove Dowel Pins
Center-groove pins are often used in place of clevis pins or to create T-handles. The grooves pinch shut when pressed into a hole, creating tension and holding the pin in place. The grooved center locks pins in position, while the smooth ends act as a pivot. For the best fit, the hole should be equal to or slightly larger than the diameter shown. The ends are chamfered for easy insertion. Pins are made of zinc-plated steel for good strength and some corrosion resistance. Breaking strength is measured as double shear, which is the force required to break a pin into three pieces. Also known as type E pins.
