Re-Sharpening Instruction
| For Wood: Hard and soft Plastic: Acrylic, PVC etc Soft non-ferrous metal sheet: Aluminum, Copper sheet Drywall Most common construction materials Not to be used for masonry Hex shank for any chuck or "quick change" chuck
Wood, drywall: curved bore paths blind holes are a snap fast chip removal
No slippage assures accurate placement of hole.
Plastic: no melting, the same clean cut as wood, no cracking-start slow Plastic, Soft non-ferrous metal and metal sheet: less heat prevents drill "sticking" efficient chip removal no bur left with less pressure and suggest soft backing material
Convent hole near tip for pulling wire through the hole with the bit that made the hole.
We do not recommend ferrous metal as a general practice. When encountering ferrous metal sheet, minimal force should be applied to the bit, which helps preserve the cutting edges.
Position bit on drilling surface before start drill
