High Quality 6 mm 1/4 Rotary Files Bits, SB/SC/SD Series (Electric Burr Grinder)
SB cylinder, SC cylinder ball-nose and SD ball heads with full dimension table – pick the exact tool number for the job.
Design and Construction
The SB/SC/SD series is published with a complete dimension table (tool number, cut diameter, cut length, shank diameter, overall length) so purchasing and production reference the same numbers. Integral YG carbide, double cut, 6 mm shanks.
How It Works
Pick the code from the table: SB for flat work, SC for work with a bottom corner, SD for full-radius blending – all at 6,000-50,000 RPM depending on diameter.
Applications
Production deburring standards, tool-crib standardisation, OEM line maintenance.
Field Cases
- Tool crib: standardised on SB and SC codes so every bench orders by tool number, not by description.
- OEM line: SD-6 blends a cast-aluminium housing radius on a 40-second cycle.
- Contract shop: the published table shortened quoting time – cut diameter and length are on the page.

Material Comparison: SB vs SC vs SD – the Cylinder Family Decoded
Three cylinder-family codes, three behaviours – typical industry data:
| Code | Contact | Unique Skill | Typical Job |
|---|---|---|---|
| SB cylinder | Flat faces, edges, shoulders | Flat end cuts corners too | General steel work |
| SC cylinder ball-nose | Flat work ending in a radius | Bottom radius protects pockets | Pocket and step work |
| SD ball | Full concave blending | Sphere contact everywhere | Radii and dies |
Delivery Scope
Burr in plastic case; the dimension table is supplied with quotations and packing.
