[Package] This Carbide grit hole saw kit includes: 3-1/4” carbide drill bit, 1pcs of 0.34” Hex shank mandrel, 1pcs of Ø0.25”x3.5" carbide tipped pilot drill bit.

[Application] This Carbide grit hole saw kit is for Air Brick, Fiber Cement Siding, Backer Board, Stucco, Plasterboard, Hardy Plank

Cutting depth: Up to 1-1/2”

[Advantage ] Cuts more than standard bi-metal hole saw for Hardy Plank, Hardwood, MDF, Up to 30 times.

[Advantage ] Deep Cutting : Up to 2.36 ”. Drill through thick material easily. The big slot design and special teeth are to remove the plug easily.

[Advantage] The carbide is made by a famous European company, Automatic welding machine ,Grinding edge machines are from German. Teeth are more shape ,stability , durability and a longer life.

[Advantage 1] Dry drilling , no water, very convenient(it’s better for cool drilling, more cuts, longer life, keep more sharp).

[Advantage 2] Max cutting depth: 6”（150mm）;

[Application] Ideal for marble , Granite, Ceramic, Tile, Porcelain, Stucco, Masonry, Brick, Stone (not for wood, metal).

[Advantage 1] Can cuts more thin metal. Not only for wood. It's Real bi-metal hole saw .

[Advantage 2] It’s much better for cutting soft material. When cutting the thick wood(thickness ≥ 0.12”)，the speed of newly- designed sharp teeth is faster than the standard one by 50% . The New Smart Slot : Removing the plug easily, it’s faster than standard one at least 3 times .

[Advantage 3] The teeth is High-Speed Steel material. The Bi-metal strip is made by laser welding and vacuum heat treatment machine. Cuts precise, cleaner hole. It’s smooth and longer life.

[Package] 1 x 6" hole saw; 1 x big mandrel(0.43” shank); 2 x HSS pilot drill bits; extra 1x 3M measure tape.

[Application] Ideal for Wood, Plasterboard, PVC, MDF, Drywall, Thin Aluminum & Copper (NOT for black Metal). For home projects on air ducts, speakers, ceiling lights, etc.

[Advantage 1] Max cutting depth: 1.2”(30mm).

[Advantage 1] Can cuts more thin metal. Not only for wood. It's Real bi-metal hole saw .

[Advantage 2] Cutting depth: Up to 1-1/2”(38mm)

[Advantage 3] The teeth is High-Speed Steel material. The Bi-metal strip is made by laser welding and vacuum heat treatment machine. Cuts precise, cleaner hole. It’s smooth and longer life.

[Advantage 1] The specially kit includes 6-3/8” high speed steel hole saw with extra dust bowl. It’s more helpful for drilling the ceiling tile and wood. It’s more clean.

[Advantage 2] Longer life: Can drill 30 holes(up to) in 0.12" low carbon steel plate. Max cutting depth: 1-1/2”(38mm)

[Advantage 3] Bi-metal strip is made by laser welding machine and vacuum heat treatment, providing better hardness, strength, and longer life.
