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.

Full-Groove Dowel Pins
Grooves run the full length of these pins for a firm hold that won't spin. Use them in place of standard dowel, spring, and taper pins to fasten parts. The three grooves pinch shut when pressed into a hole, creating tension to lock pins in place. For the best fit, the hole should be equal to or slightly larger than the diameter shown. The ends are chamfered for easy insertion. Breaking strength is measured as double shear, which is the force required to break a pin into three pieces. Also known as type A pins.
Pins with parallel grooves fit more tightly than pins with tapered grooves, so they’re less likely to loosen from vibration. However, they require more force to insert. Pins that meet ISO 8740 comply with international standards for parallel-groove metric dowel pins.
Zinc-plated steel pins have good strength and some corrosion resistance.

Half-Groove Dowel Pins
These pins make good hinges or pivots. The grooves pinch shut when pressed into a hole, creating tension and holding the pin in place. The grooved half locks pins in position, while the smooth half acts 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 H pins.
Tapered pins are good when part of the assembly must be a free fit.
