HSS M42 4-1/2 BI-Metal Hole Saw Kit for PVC, Drywall, Wood, Plastic, Gypsum Board & Rubber

Product Description

Made with M42 and 8% cobalt, this excellent bi-metal hole saw features a robust construction with variable toothing on a flexible special steel body. The high quality teeth and teeth geometry provide high cutting performance and tool life.

Using lubricant while working with metals can help increase the tool life.

The BI hole saw is constructed with M42 and has a hardness of 67-70 HRC, offering good cutting performance for easier and smoother drilling.

The center drill bit included is of higher quality, featuring a sharp split tip that enables faster and stronger drilling.

The mandrel and spring have been designed for easy use, with the hex shank supporting 11mm (7/16") drill chuck or larger chuck. The spring helps eject waste material, making work more comfortable.

This hole saw is widely used for a variety of projects, including cornhole boards, air ducts, ceiling lights, drywall, wood, plastic, gypsum board, aluminum, soft thin metal, and rubber.

Materials that can be cut with the bi-metal hole saw include thick wood, plywood, plastic, drywall, soft plaster, cornhole boards, and thin metals.

When cutting, it is important to keep the drill bit in contact with the cutting surface straight at a low speed to achieve a smooth and clean cut. Cutting oil or water should be used when cutting metal.

If the desired size is not available, additional models will be introduced to the market in the near future.

Attention should be paid to safety precautions such as avoiding touching the hole saw immediately after use due to high temperatures, adding coolant or water when drilling metal, and stopping immediately if the hole saw works abnormally during operation.

The hole saw dimensions are as follows: Cutting Dia: 114mm | 4-1/2"; Shank Dia: 11mm | 7/16"; Hole Saw Depth: 38mm | 1-1/2".

With raw materials from a Japanese brand, this hole saw offers an extremely long life span. The saw teeth are made of M42 high-speed steel with a hardness of ≥65HRC for durability and resistance to rust and corrosion.

The hole saw height is up to 1.5", with tooth height ranging from 1.5mm-1.8mm, making it suitable for cutting a variety of materials.

Professional use is made easy with the variable tooth pitch and reduced vibrations and noise during cutting.

Efficient and smooth cutting is achieved thanks to the high performance of M42, providing flat and smooth kerfs.

Safety precautions should be taken while using this tool to protect personal safety. Goggles, masks, ear plugs, and gloves should be worn to reduce risks while working.
