Built for fine deburring, precision finishing, and small-part material removal, the Dotco 12R0410-16 Inline Precision Grinder combines a 0.1 HP pneumatic motor with a high-speed 60,000 RPM output for detailed work with compatible mounted points, carbide burs, and abrasive accessories. The 3/32" collet holds small-shank tooling used for close-tolerance finishing, while the inline body gives the operator pencil-style control for careful edge work and surface blending.
Part of the 12-04 Series, this Dotco precision grinder features a composite housing and rear exhaust configuration. The composite body helps reduce tool weight compared with all-metal housings, while the rear exhaust routes spent air away from the work surface. Its 60,000 RPM speed makes accessory speed rating critical; always match the grinder with abrasives rated for the tool’s maximum operating speed.

FAQs:
- Q: What accessories fit the Dotco 12R0410-16?
A: This grinder uses a 3/32-inch collet, so accessories must have a compatible 3/32-inch shank. Always confirm the accessory’s maximum RPM rating before use. - Q: Why is 60,000 RPM used on a precision grinder?
A: High spindle speed supports very small accessories and fine material removal. It helps the tool perform detail work, deburring, and controlled finishing where larger die grinders would be too aggressive. - Q: Can this grinder use 1/4-inch shank carbide burs?
A: No. This model is listed with a 3/32-inch collet, so 1/4-inch shank tooling will not fit unless the manufacturer offers an approved alternate collet configuration. - Q: What safety check is most important before using abrasives with this grinder?
A: Confirm that the mounted point, bur, or abrasive accessory is rated at or above 60,000 RPM. Never use an accessory below the tool’s maximum speed rating.
