Air pencil grinders are powered by compressed air to deburr parts, grind the insides of holes, smoothen & finish moulds and blend contours for woodworking & construction applications. Raptor Supplies is a trusted seller of air pencil grinders from brands like Chicago Pneumatic, Dotco, Dynabrade, Ingersoll-Rand and Speedaire. Air pencil grinders from Dynabrade feature a vibration free design which reduces operator fatigue and allows precise deburring. They come equipped with a high speed motor controlled with a patented governor to provide constant speed under load. The efficient tube design uses a maximum airflow of 8 SCFM at 90 PSI for enhanced operation. These air pencil grinders feature a guard collet with a tactile warning which keeps the fingers close to the workpiece and away from the collet & burr. Chicago Pneumatic air pencil grinders are ideal for tight space applications as they are lightweight and easy to handle. These pencil grinders come equipped with a silencer hose which allows operation at a very low noise level of 71 dB(A). They feature a high power to weight ratio which ensures reliable operation and free speed of 60000 RPM.
