Hole saw and core drill, bi-metal hole saw, metal hole saw, annular core drill for hole sawing in wood, drywall, plastic and flexible metal (135mm) L

PROFESSIONAL QUALITY: Made of bi-metal high-speed steel (HSS), heat-treated carbon steel, oil and rust resistant, with high heat and wear resistance. The high-speed steel teeth provide a fast and clean cut, offering the advantages of being rust-resistant, durable, robust, long-lasting, and reusable.

ADVANTAGES: The teeth have a 30° right angle, which is extremely sharp and can cut and drill quickly, saving energy. The inner wall of the drill bit is thick and of good quality.

USER-FRIENDLY DESIGN: Numerous chip holes prevent sawdust from clogging during use and from cutting at the deepest point.

After the cut, a small spring automatically rebounds onto the cut round blocks of wood, making it very convenient to use. WORKING METHOD: The user can keep the drill bit straight in contact with the cutting surface, slow down the speed, and take a little time with the saw to achieve a smooth and clean round cut. WIDE APPLICATION: The bi-metal saw is an ideal tool for various jobs. Suitable for cutting wood, plastic, machinable metal, wood with nails, plywood, pipes, and steel. It can be used in hand drills, bench drills, and other flat drilling equipment.

MADE OF PREMIUM M42 HSS, ROBUST AND DURABLE

Keep the drill bit steady while drilling, otherwise the center drill bit may break due to excessive shaking.

Please start drilling at a slower speed, otherwise the center drill bit may be damaged the first time you use it.

Read more: the wider the saw's bell, the lower the drill speed, which can prevent the center drill bit from breaking.

The circular hole cutting machine has low cutting resistance, which improves the opening speed. The machine head adopts an arc-shaped curved design, which has low consumption and high efficiency.

The new chip removal flute can quickly remove chips.

The hole saw is smooth and easy to use. After drilling, the drill spring will automatically push the blade out of the saw.
