Hole Saw Bi-Metal 38 mm Verto 60H930

Bi-metal hole saw 38 mm Verto 60H930 is designed for cutting precise circular openings in metal and other common construction materials. The tool features a bi-metal tooth design that combines high-speed steel cutting edges with a flexible backing, improving wear resistance and heat tolerance during continuous cutting operations. The saw fits standard drill arbors and can be used with both handheld drills and drill presses for tasks that require a clean 38 mm diameter hole.

Advantages

The bi-metal construction provides extended blade life compared with standard carbon steel saws and resists overheating under heavy load. Teeth geometry is optimized for faster cutting and reduced burr formation, producing cleaner hole edges and less post-processing. Compatibility with common drill arbors makes setup quick and allows use across a variety of power tools. The 38 mm diameter is suitable for many installation and assembly tasks where consistent hole size is critical.

Suitable for

• Plumbing pipe penetrations and fittings
• Electrical conduit and cable gland openings
• HVAC ducts and mounting holes for fasteners
• Cabinetry and furniture work requiring circular cutouts
• Light to medium-duty metalwork, sheet metal and thin plate

Key specifications

• Cutting diameter: 38 mm
• Tooth material: bi-metal high-speed steel edge with flexible backing
• Suitable materials: steel, stainless steel (thin gauge), aluminium, wood, plastics
• Compatibility: standard drill arbors and drill presses
• Typical use: hand drills and drill press applications

How to use

Secure the hole saw to a compatible arbor and tighten according to the arbor manufacturer’s instructions. Mark the center point of the required 38 mm opening and pilot-drill a guide hole if needed for accurate positioning. Operate the drill at a moderate speed suitable for the material being cut, applying steady pressure without forcing; use cutting lubricant when working with metals to reduce heat and extend blade life. After cutting, remove the slug and deburr the hole edges if required.

Usage recommendations

For best results when cutting metal, use cutting oil and run at lower speeds to minimize heat build-up. When cutting thicker or hardened steel, make multiple shallow passes rather than attempting the full depth in a single cut. Always wear appropriate personal protective equipment and secure the workpiece before drilling.
