BIT SHARPENING

SCREWDRIVER

LAWN MOWER BLADE

WARNING:

Never sharpen or grind anything made of aluminum.

Grinders remove material rapidly so pressure is the key to efficient grinding.

The proper way to sharpen a tool and avoid overheating is:

Keep the object in constant motion, moving it at an even pace.

Never force a tool against the grinding wheel.

Keep the tool cool by using either a cooling tray or a pan of water.

The grinding wheel should rotate “into” the object being sharpened.

Note: Excessive pressure may damage the tool, cause the motor to overheat, and prematurely wear down the grinding wheel.

This technique requires considerable practice, so take your time and make a few “dry runs” first with the grinder off. Be sure to maintain the original cutting edge angle as this is important to the efficiency of your bits. One work rest has a V-groove angled to fit most drill bits.

WARNING:

LAWN MOWER BLADES

Excessive pressure on a cold wheel may cause the wheel to crack.

The following recommendations will help you sharpen specific tools:

TWIST DRILL BITS

See Figure 8.

Drill bits are best sharpened on a sharpening jig (available at most hardware stores). Begin on one side of the point at the existing angle, then twist the bit while maintaining contact with the grinding surface. Sharpen only the tip.

See Figure 9.

Lawn mower blades are usually sharpened on only one edge and dressed up slightly on the other. Perform this sharpening process on both cutting ends of the blade. After sharpening, be sure to balance the blade by removing additional material.

CAUTION:

An unbalanced lawn mower blade may cause excessive vibration which will damage the lawn mower.
