RECEIVED PACKAGE COMPRISE -- In our hole saw storage case, you'll receive 1 x 6-1/4" bi-metal hole saw, 1 x 1/2" hex shank arbor, 3 x 1/4" center drill bits, and 1 x Allen wrench. Tips: ①Remember to Begin drilling slowly, ②Applying even pressure on the drill, and maintain a low speed to prevent overheating and ensure smooth cutting, ③Periodically withdraw the hole saw to remove debris and prevent binding.

CONSTRUCTION ADVANTAGE -- Our bi-metal hole saw is expertly constructed from premium carbon steel and M42 high-speed steel. Cutting edges made of high-speed steel, electron-beam welded to a carbon steel body, provide the required hardness and wear resistance for cutting. While the carbon steel body offers flexibility and impact resistance. The unique blend of materials delivers the ability to withstand high cutting temperatures, reduces the risk of breakage and extends the life of the hole saw.
