6-1/2 inch HSS Bi-Metal Hole Saw, Red Finish Corn Hole Cutter 165 mm for Wood Boards, Soft Metal Sheet, Drywall and Plastic

✔【FAST & ACCURATE】 The increased hardness of the carbide technology and optimized tooth geometry allow our hole saw to provide faster cutting speed and more accurate than standard hole saws cutting everything from wood and plastics to aluminum, steel, cast iron, and stainless steel. ✔【PREMIUM MATERIAL】 The surface layer of bi-metals is typically stronger than an alloy of similar materials as it is made of M42 alloy material, which is featuring high hardness(≥64HRC) to ensure the surface layer durable and rust-proof. The bi-metallic cutting teeth is layered with high speed steel, that increases their hardness and durability, and gives the hole saw excellent cutting ability. ✔【MORE EFFICIENCY】One of the chief advantages of using a hole saw over a conventional drill bit is the hole saw’s efficiency. Due to the fact that so little of the total amount of material being removed is actually cut, much less power is required, so that you save energy and increase the battery life of your portable power tools. ✔【VARIETY OF SIZE】 The another advantage of our prodcuts is the hole saw’s ability to cut a greater variation of hole sizes. There are a wide range of diameters available on our store that can cut with ease when compared with a twist drill or spade drill trying to perform the same task. ✔【FRIENDLY CUSTOMER SERVICE】 we promise to provide 60 days free return and replace service, and guarantee to make our customers satisfied with every purchase. If you got any problem with the products, please contact us first via e-mail, we will reply you asap in 12h. What are the hole saws used for ?
They are used to cut perfectly round holes in a wide variety of materials. Widely used in plate holes, household wood, galvanized pipe, fire hose, plastic, gypsum board and other opening operations.

Power Drill Required
A hole saw is designed to attach to a POWER DRILL (including pistol drill, bench drill, vertical drill presse) and rotate at a high speed. As the saw spins, the teeth cut into the chosen material, removing a circular piece (slug) as it saws through.

BENEFITS & ADVANTAGE
BI-Metal + High Speed Steel(HSS) Extremely fast sawing with minimal expenditure of force
High concentric and side-stroke precision
They can cut holes with much larger diameters than traditional drill bits.
Because they only cut out the perimeter line of the hole, they are much more EFFICIENT than a spade drill or twist drill.

Common Applications
Steel, stainless steel, cast iron, copper, bronze, aluminum, wood and plastic.

INSTRUCTIONS
Pre-drill using light contact pressure. Continue drilling with minimal, even pressure; avoid oscillating while drilling.
Follow speed guidelines and use coolant.
Allow hole saw to “air” when using with wood and wood alternatives.
The saw comes to a complete stop on your material before pulling it away.

* Note:
Due to manual measurement and production batch is not the same, the size, weight, color will get difference (within 3%) of the normal case.
