The long-lasting carbide material can provide consistent cuts with high precision. BulletPoint3 : Feature - The teeth are specially designed with three cutters (outer cutter, middle cutter, and inner cutter). Three-edged combination teeth provide faster cutting speed, low cutting resistance, longer service life, and less clogging, resulting in smoother and more efficient cuts. BulletPoint4 : Applications - The hole saw set can cut precise and clean holes in stainless steel, mild steel, copper, iron, aluminum, hard metal, wood plastic, and FRP. Widely used in pipes, tubing, cabinets, doors, furniture, and metal sheets. NOT used for ceramic tile, concrete, stone. BulletPoint5 : Note - Carbide hole saws are most effective for cutting through materials up to 5mm thick. Use a lubricant or cutting oil on the cutting edge to reduce friction and prevent overheating. Apply pressure gradually, control speed, and clear the debris from the teeth frequently.

The carbide hole saw teeth are specially designed with three cutters, including outer cutter, middle cutter, and inner cutter.

The hole saw set can cut precise and clean holes in stainless steel, mild steel, copper, iron, aluminum, hard metal, wood plastic, and FRP. Widely used in pipes, tubing, cabinets, doors, furniture, and metal sheets. Carbide hole saws are most effective for cutting through materials up to 5mm thick. NOT used for ceramic tile, concrete, stone. The hole openers are suitable for hand-held drills, drill presses, bench drills, magnetic drills. A drill press provides precise control over the drilling process, making it an excellent choice for drilling multiple holes or drilling through thick materials. Keep the hole saw steady while drilling. Notice: If the material thickness is over 5mm, the cutting speed may slow down and the teeth may start to wear down more quickly. Use a lubricant or cutting oil on the cutting edge to reduce friction and prevent overheating. Apply pressure gradually and control speed. Clear the debris from the teeth frequently to avoid clogging and ensure efficient cutting.
