Application
MATERIALS:
• soft, hardwood 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 board, Eternit®
• plastics (Trespa®, PVC, nylon, polyester)
• fiberglass and acrylic glass
• soft tiles (surface hardness ≤6 Mohs), solid bricks and bricks with cavities, aerated concrete blocks, lightweight aggregate blocks and breeze blocks, soft density lime-sandstone building blocks (max 30 N/mm2 hardness); for hardness >30 N/mm2 use the 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 results.
The percussion/hammer action mode must be turned off when using these hole saws.
