Hole saw for metal MODECO MN-61-411 bi-metal 30 mm

MODECO MN-61-411 bi-metal hole saw with a 30 mm cutting diameter is designed for cutting precise circular openings in metal sheets and similar materials. Manufactured from bi-metal construction, it combines high-speed steel cutting edges with a flexible body to improve durability and resistance to heat during prolonged cutting operations. The tool is intended for use with compatible drills and drill stands where accurate round holes are required for installations and metalworking tasks.

Advantages

The bi-metal construction provides a balance of wear resistance and toughness, extending tool life compared with plain-carbon alternatives. A 30 mm cutting diameter delivers a standardized size for pipe entries, cable glands, and fastener clearances. The saw’s teeth geometry and material composition help maintain cutting performance under elevated temperatures and repeated use. Compatibility with common drill arbors and pilot drills allows straightforward mounting and stable operation.

Suitable for

• Drilling circular holes in sheet metal and thin steel plates
• Electrical and HVAC installations requiring conduit or gland entries
• Metalworking tasks where precise round openings are needed
• On-site installation work with portable drills and drill stands

Key specifications

• Cutting diameter: 30 mm
• Material: bi-metal (high-speed steel teeth bonded to flexible body)
• Intended material: steel and other ferrous materials, sheet metal
• Typical mounting: compatible with standard drill arbors and pilot drills
• Recommended use: manual electric drills and drill stands for stable cutting

How to use

Secure the hole saw to a compatible arbor and pilot drill according to the drill and arbor manufacturer’s instructions. Mark the hole center on the workpiece and, where possible, clamp the material to prevent movement. Start drilling at low to moderate speed to allow the pilot to engage and the saw teeth to cut cleanly; apply steady pressure without forcing the tool. Use cutting lubricant or coolant when drilling thicker or harder metals to reduce heat build-up and extend tool life. After cutting, remove burrs and inspect the hole for required tolerances.

Usage recommendations

For best results when cutting steel or other hard metals, use appropriate cutting fluid, keep drill speed moderate, and ensure the workpiece is securely clamped. Replace the hole saw if teeth become visibly worn or damaged to maintain hole quality and operator safety.
