HIGH-QUALITY MATERIALSThe hole opener is made of M42 high-speed steel and bimetal, and the cutting part has higher hardness (≥64HRC) and higher toughness. The arc design has high concentricity accuracy, uniform tooth edge, rust-proof, wear-resistant and long service life. It has excellent performance and higher cutting strength than other hole saws on the market.

FAST AND ACCURATE CUTTINGThe increased hardness brought by carbide technology and the optimization of product tooth shape make our hole saws provide faster cutting speed. The high-speed steel blade drill saw attachment provides impact-resistant teeth and prevents teeth from falling off, which is more accurate than standard hole saws, and the difference in cutting diameter is allowed to be less than one millimeter.

EASY TO USEThe unconstrained clean edge design makes cutting smooth and fast. The newly designed chip removal hole can quickly remove chips without causing cracks and stuck parts, and the wood chips are removed more smoothly. The spring on the drill bit will automatically push the wood chip disc out of the saw immediately after the hole cutting is completed.

WIDE APPLICATIONThe hole saw is suitable for cutting wood, plastic, mild steel, stainless steel, cast iron, bronze, copper, aluminum, etc. In addition, it can also cut holes for can lights, recessed lights, air ducts, ceiling lights, speakers, etc. Suitable for: bench drills, drill presses, gun drills, various hand drills, etc.

NOTEWhen using the hole opener kit for a long time, please control the speed appropriately, RPM≤1000, which is easy to cause high-speed wear of the hole opener. The surface of the product is coated with a thin layer of protective oil (anti-oxidation, anti-rust), please be careful not to get it dirty and check the condition of the hole opener.
