Industrial Straight Die Grinder 1.0 hp
The Dynabrade 52667 is a straight die grinder built for metal finishing, deburring and weld preparation in professional workshops. Its 1.0 hp motor delivers 15,000 RPM free speed through a 1/4 in collet. The composite handle reduces weight and vibration during extended use. A 3/8 in NPT female air inlet and 3/8 in minimum hose size support the required 90 psi operating pressure.
Upgrade From Lower CFM Tools
This grinder demands 39.0 CFM at full load and averages 9.75 CFM over a 15 second run, so it replaces smaller grinders that cannot sustain material removal on hardened steel or heavy castings. The jump is worth it when your current tool stalls under load or lacks the airflow capacity for continuous porting work. Gearless construction eliminates gear maintenance and reduces downtime. Buyers with compressors below 39 CFM peak flow should not expect full performance.
Sustained Load Behaviour
Under continuous operation the anti clog exhaust baffling maintains consistent rear exhaust flow without back pressure buildup. Ball bearing spindle support keeps runout low during long sessions on tough alloys. The throttle lever provides direct control without variable speed circuitry that can limit peak torque. Composite housing resists heat soak better than aluminium bodies during hour long grinding cycles.

Questions about this item
What size air hose and inlet fitting does the 52667 require?
The grinder needs a minimum 3/8 in hose and connects via a 1/4 in NPT air inlet fitting.
How do I attach accessories to the 1/4 in collet and what is the common mistake?
Insert the accessory shank fully into the 1/4 in collet and tighten the collet nut securely; the frequent error is leaving the shank seated too shallow.
When should I service the ball bearings on this straight die grinder?
Inspect the ball bearings if vibration increases or free speed drops below 15,000 RPM at 90 psi; replace them when wear causes excessive run-out.
