Tight-Tolerance Multipurpose
Oil-Hardening O1 Tool Steel Rods
- Yield Strength: 50,000 psi
- Hardness: Rockwell B90 (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment:
Inch sizes: Rockwell C65
Metric sizes: Rockwell C62 - Specifications Met: ASTM A681
Ready for turning in a lathe, these rods are precision ground to a tight diameter tolerance. They’re also known as drill rod. Often used for dies, punches, and gauges, O1 tool steel is an oil-hardening material that resists wear and abrasion.
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.
| Dia. | Dia. Tolerance | Drill Bit Size | Lg. | Mechanical Finish | Straightness Tolerance | Each | |
| 0.3281" | -0.0002" to 0" | 21/64" | 4 5/8" | Precision Ground | 0.001" | 00000000 | 00000 |
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.

Tight-Tolerance Easy-to-Machine W1 Tool Steel Rods
- Yield Strength: 50,000 psi
- Hardness: Rockwell B95 (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C65
- Specifications Met: ASTM A686
These rods, also called drill rod, are ground and held to strict diameter and straightness tolerances. They are ready to be turned in a lathe. With lower amounts of alloy elements than other tool steels, W1 offers excellent machinability. This water-hardening material is often used for hammers, files, taps, and reamers. These rods are decarb-free for a uniform surface that will consistently accept heat treating.
