Feature

●【Construction Grade】- Hole Saw is made of HSS M42 & high speed steel, rust-proof, impact resistance, wear resistance. With higher hardness, higher toughness, higher cutting strength and stronger resistance. Well made, sharp, hard, lasting.
●【Efficient & Smooth Cutting】- Hole Saw with the non-binding clean edge design. Ultra sharp serrations ensures smooth and clean cutting of the hole saw blade. The spring on the drill would automatically pushes the disc out of the saw immediately after completing the hole.
●【Product Contain & Size】- 1 Set M42 Bi-Metal Hole Saw. Cutting Depth: 32mm/1.25"; Shank Diameter: 11mm/0.44"; Total Length of Shank: 118mm/4.64".
●【Versatile Use】- The Hole Saw is widely used in wood, PVC board, plater board, plywood, duct, plastic, drywall, soft plaster, corn hole boards and thin metals. Perfect for household projects.
●【Warm Reminder】- Keep the drill in straight contact with the cutting surface. Afterwards you must turn slowly, keep it cool and lubricated, and apply a slow, steady downward pressure. Workers should wear corresponding protective equipment.

Description

HSS BI-Metal Hole Saw

From the Manufacturer:

The Bi-Metal Hole Saw is crafted from the highest quality bi-metal. The teeth are attached to a carbon steel body by a process called electron beam welding.

The result is a tool composed of two types of metal welded edge-to-edge - also know as bi-metal construction.

Because the Hole Saws are engineered and manufactured for exceptional sharpness and durability, they will cut much more than wood.

These saws will also cut holes in aluminum, copper, iron, stainless steel and zinc. The hole saws also have a tooth "pitch" that varies from 4 to 6 teeth per inch.

This reduces harmonics and improves performance. Also, the variation in depth of gullets between the blades teeth provides more efficient chip clearance, giving you greater cutting speed.


Sharp Teeth The teeth is sharp and vibration is less, which enables more stable operation and make the hole can be cut with quick speed and balance.	Excretory Pore Each drill bit is equipped with small holes around the wall, which can improve the speed to expel the chips at work.	Locking Screw Effective anti-skid, stronger load torque.
