GREAT PERFORMERS withstand the test of time.  Armstrong Band Saw Sharpeners have passed this test and continue to serve saw filers, as they have for more than 50 years. Armstrong machines are prized worldwide for their precision performance, rugged dependability, ease of operation and readily available spare parts. All adjustments are positive and easy to make for many years of fine, trouble-free service.


Rugged steel and cast-iron construction

Durability to deliver years of precision performance

Extra power for heavy grinding

Large grinding wheel motor (2 HP motors supplied on No. 4 sharpeners equipped for three phase current; 1 HP grinding wheel motors for No. 2 sharpeners or when single phase electrical current is specified for No. 4 sharpeners) and 1 HP action motor for heavy grinding and large saws.

Improved grinding wheel arbor assembly

The grinding wheel arbor is machined from a single bar; there are no pressed joints to loosen or run out. Tapered roller bearing pillow blocks are now standard on all No. 4 Armstrong sharpeners. Poly-V belt drive to grinding wheel arbor for low vibration, no-slip grinding.

Multiple, over-sized UHMW cams

Smoother action, longer wear and quick, simple change-over from one tooth shape to another.

Lower overall costs

Precision grinding saves on grinding wheels, spare parts, and saw consumption!

All Armstrong Band Saw Sharpeners come standard with:
Enhanced Grinding Wheel Arbor Assembly

Larger motors, one-piece arbor, heavy-duty pillow block bearings and non-slip, low-vibration poly-V belt drive all contribute to precision grinding for extremely sharp saws and less chance of burning that can lead to cracks.

Improved Heavy-Duty Rocker Arm Assembly

These stronger rocker arms increase the life of your grinding wheels and provide a much smoother grind on your saws.  This improved design helps achieve sharper saws with less chance of gullet cracks.


Armstrong Sharpeners are designed to use up to three pairs of cams, allowing the operator to change tooth designs simply by moving a lever and locking the cam shaft into a new position.  Each pair of cams is individually adjustable to enable the filer to produce a precise tooth shape.  One pair of cams is supplied with each sharpener.

Carbide Faceplate

An oversized, self-cleaning carbide faceplate is standard on all new band saw sharpeners. This faceplate has carbide strips set out from the steel backing plate for a wear surface that stays clean and can be reground.

Safety Guards

Safety guards, covering the pulley, belts and the grinding wheels, are standard on all sharpeners.

Adjustable Post Brackets

For each machine, Armstrong provides both manual and automatic post brackets. Automatic post brackets raise or lower together with the saw carriage as the saw height is adjusted.
