HOW TO SHARPEN WITH A DOUBLE-SIDED DIAMOND CREDIT CARD
UK´s No1 seller Double sided Fine / Coarse diamond stone.
Always sharpen the router on the flat side Ð never touch the profile otherwise you will change the shape of the cutter.
Sharpen the cutter from new with three or four light strokes to each face. Count the amount of strokes on one side of the cutter and then repeat to the other to keep it in balance.
Keep the cutter sharp so that it works as it is designed to do. Do not wait until it is blunt before sharpening as this will require excessive honing or professional re-sharpening.
Sending cutters away for professional re-sharpening may result in losing excessive surface material.
Regular maintenance will result in the life of the cutter being prolonged.
Narrow thickness of the Credit Card sharpener (0.8mm) allows easy access to small and anti-kickback round form cutters.
Fine (600 grit) for tungsten carbide (TCT).
