Engineered for precision and durability, this 6-piece 16-32mm steel carbide-tipped metal drilling crown drill bit set delivers clean, accurate holes in tough materials. The carbide-tipped teeth maintain sharpness longer than standard bits, providing superior cutting performance and extended tool life for demanding metal and woodworking projects. Features and Benefits
- Carbide-Tipped Steel Teeth - Provides exceptional hardness and heat resistance for drilling through hardened steel, stainless steel, and cast iron without rapid dulling.
- 6-Piece Size Range (16mm, 20mm, 25mm, 29mm, 30mm, 32mm) - Covers the most common hole diameters needed for plumbing, electrical, and general fabrication tasks.
- Full Heat-Treated Alloy Steel Body - Ensures the hole saw body withstands high torque and prevents deformation during aggressive cutting.
- Deep Cutting Depth Design - Allows for efficient cutting through thicker materials in a single pass, saving time and effort.
- Included Pilot Drill Bits - Guarantees precise starting points and prevents the crown from walking on curved or hard surfaces. Applications
- Metal Fabrication - Creating clean holes for conduit, piping, or mounting hardware in sheet metal, angle iron, and steel tubing.
- Plumbing and Electrical Work - Cutting precise openings for sink drains, pipe fittings, and electrical box installation in wood and metal studs.
- DIY and Woodworking - Boring large diameter holes for dowels, cable routing, or custom furniture projects in hardwood and plywood. Note
For optimal performance and longevity, use at recommended RPMs with cutting fluid when drilling metal and clear chips frequently.
