MAKITA D-17251 Bi-Metal Hole Saw 20 mm

MAKITA D-17251 BIM Hole Saw 20 mm
The MAKITA D-17251 hole saw is a cutting tool for creating 20 mm circular holes, made from Bi-Metal (BIM) material, an alloy steel designed to enhance efficiency and lifespan:Cutting Edge: Made from High-Speed Steel (HSS) to provide high strength and wear resistance when cutting hard materials such as metal.Hole Saw Body: Made from more flexible alloy steel, helping to reduce the risk of breakage under torque or impact.Vari-Pitch Teeth: The hole saw features a variable pitch tooth design (4/6 Vari-Pitch Tooth Design). This feature significantly reduces vibration and noise during drilling, resulting in significantly smoother and faster operation.

Specifications
- Bi-Metal Durability: Ensures the strength of HSS cutting edges and the flexibility of the hole saw body, providing a longer service life compared to standard hole saws.
- Reduced Vibration (Vari-Pitch): Vibration-reducing tooth design ensures smooth drilling, reducing strain on both the tool and the user.
- Drilling versatility: Capable of drilling almost every type of material that installation technicians encounter on a daily basis
- Chip evacuation efficiency: The teeth and overall design allow chips to be easily cleared, preventing heat buildup

Applications & Usage
- Electrical installation: Drilling holes for conduit or small electrical equipment requiring a 20 mm hole
- Metals: Drills mild steel sheet, aluminum, copper, brass, and stainless steel sheet (using low RPM and coolant).
- Woodworking: Drilling holes in softwood, plywood, and gypsum board
- Plastics: Drilling PVC pipes, plastic sheets, and composite materials
