Medium-duty pneumatic pencil grinder

The Chicago Pneumatic CP9104Q is a straight pencil grinder built for medium-duty material removal. It suits technicians who need a compact air tool for deburring, polishing or light grinding in tight workspaces.

60 000 RPM maximum speed

The motor reaches sixty thousand revolutions per minute, which determines whether the tool can handle the abrasive or carbide accessory you plan to run. Verify that your consumable is rated for this speed before use.

0.1 hp output with 2.5 m/s² vibration

The grinder delivers zero point one horsepower through a ball-bearing spindle while producing two point five metres per second squared of vibration. Rear exhaust directs air away from the workpiece and the twist throttle lets you modulate power without a separate lever.

Questions about this item

How does 0.1 hp feel when I am grinding metal?

The 0.1 hp motor delivers enough torque for light deburring and finishing tasks on steel or aluminium without stalling under normal hand pressure.

What does the 1/4 in NPT air inlet limit in daily use?

The 1/4 in NPT inlet requires a matching coupler and hose; it caps airflow to what that fitting can supply, so check your compressor output matches the tool demand.

Will the 1/8 in collet accept my existing carbide burrs?

The 1/8 in collet holds standard 1/8 in shank burrs and mounted points; it will not grip 1/4 in or 3 mm shanks without a separate adapter.
