60-Degree HSS Center Drill Bits Set – Lathe Countersink Tool
60-Degree HSS Center Drill Bits – Precision Countersink Set for Lathe & Metalworking
Upgrade your workshop with this professional-grade 60-Degree Center Drill Bits Set, engineered for accurate center-drilling, countersinking, and spotting on lathes and metalworking machines. Whether you're a seasoned machinist or a passionate hobbyist, these bits deliver consistent, precise results on every pass.
Why Choose These Center Drill Bits?
- High-Speed Steel (HSS) Construction: Manufactured from premium high-speed steel for outstanding hardness, heat resistance, and long-lasting edge retention — even under heavy-duty use.
- 60-Degree Angle: The industry-standard 60° included angle ensures perfectly centered holes, ideal for lathe work, countersinking, and spot drilling on metal workpieces.
- Versatile Application: Suitable for lathes, milling machines, drilling presses, and general metalworking tasks — a must-have addition to any machinist's toolkit.
- Accurate & Consistent: Precisely ground cutting edges reduce runout and deliver repeatable, clean holes with minimal setup time. (Measurement tolerance: ±1–3 mm.)
- Great Value Set: Includes multiple bit sizes in one convenient kit, covering a wide range of center-drilling requirements without the need to source bits individually.

Frequently Asked Questions
Q: What are 60-degree center drill bits used for in metalworking?
A: 60-degree center drill bits are used to create precisely centered starting holes — known as center holes — in metal workpieces before turning on a lathe or drilling on a milling machine. The 60° angle matches the standard live and dead center angle found on most lathes, ensuring accurate and stable workpiece support during machining operations.
Q: What material are these center drill bits made from?
A: These center drill bits are crafted from high-speed steel (HSS), a material well known for its durability, heat resistance, and ability to maintain a sharp cutting edge through repeated use on metal surfaces.
Q: Are these drill bits compatible with standard lathe and drill press chucks?
A: Yes. These center drill bits feature standard shank diameters compatible with most lathe tailstock chucks and drill press chucks. Always verify the specific shank size against your machine's chuck capacity before use.
Q: What is the measurement tolerance for this set?
A: As with most precision machining tools, a manufacturing measurement tolerance of ±1–3 mm applies to this set. For critical applications, verify dimensions with calipers upon receipt.
