TECHNICAL FEATURES:
- Perfect round back plate.
- Fast & easy center drill change.
- Large chip clearance slots.
Long lasting construction grade carbide
Cutting teeth are made of a special formulated construction grade carbide which provides a longer cutting life.
Secured tooth technology
As a result of the latest technology, teeth are secured to prevent any breakage during impact with hard materials.
Materials:
- Soft, hardwoods and plywood.
- Chipboard, MDF, veneered, laminated and table top (pre-drill the laminate/melamine by using left-hand rotation for clean finishing).
- Gypsum, plasterboard, fibercement boards, Eternit®.
- Plastics (PVC, nylon, Trespa®, polyester).
- Tiles, solid bricks and bricks with cavities, aerated concrete blocks, lightweight aggregate blocks and breeze blocks, soft density limes and stone building blocks (max 30 N/mm2 hardness); for hardness >30 N/mm2 use our diamond dry hole saws.
Use the recommended speeds to get optimum lifetime. The speed affects the hole quality. Always pre-drill with the center drill to achieve best performance. The percussion/hammer action mode must be turned off when using these hole saws.
