HSS Lathe Tool Bit Grade 2500 Special Size CHUOKU — Grind Your Own Edge
Description
HSS Lathe Tool Bit Grade 2500 Special Size CHUOKU — Grind Your Own Edge
The CHUOKU grade 2500 special-size lathe tool is a high-speed-steel bit you grind to your own profile. The body is tough, crack-resistant, and heat-resistant, so it turns and shapes work accurately. Its key point is special cross-section sizes beyond the standard grades — ideal when a job needs a tool size you can't find in the standard range. Supplied by BOWMAP Industry & Tooling, Samut Prakan.

Use cases
- Grinding your own cutting edge for specific turning jobs
- OD turning, facing, taper turning, and thread cutting
- Jobs that need a special tool-bit cross-section
- Turning mild steel, cast iron, brass, and aluminium
- General turning in machine shops and parts production
Compatibility
Choose a cross-section to fit your tool post and job. Grind the rake, clearance, and cutting angles to suit the material (e.g. aluminium uses a large rake ~35–40°, brass ~0°). Set the edge to centre height for taper turning, facing, and threading so the part comes out to size and shape.

FAQ
What is grade 2500 special size?
2500 is an HSS grade for lathe tools that is tough and heat-resistant. "Special size" means cross-sections beyond the usual standard sizes — for jobs that need a specific tool size you can't get in the standard grades.
Why grind the tool angles to the material?
Tool angles decide how well the bit cuts and how long it stays sharp. The key ones are rake (helps chips flow), clearance (stops the tool rubbing), and the cutting-edge angle. Each material needs different angles — e.g. aluminium uses a large rake (~35–40°) while brass uses ~0°.
What accuracy can I get?
It depends on the machine, tool, and operator. Typically roughing/boring runs ±0.15–0.40 mm and finishing ±0.05–0.18 mm by part size.
