Hole saw MODECO MN-61-281, carbide-tipped, HEX shank, 80 mm

Carbide-tipped hole saw MODECO MN-61-281 with an 80 mm cutting diameter and HEX shank is designed for drilling circular openings in metal and other hard materials. The tool has welded carbide teeth that provide increased wear resistance and stable cutting performance. The HEX shank allows secure mounting in drills and drivers with a hexagonal arbor, reducing slippage during heavy-duty work.

Advantages

The carbide-tipped cutting edge ensures prolonged service life and consistent hole quality when working with steel, stainless steel and other tough substrates. Welded teeth maintain edge integrity under repeated use and resist chipping. The HEX shank provides reliable torque transfer and quick tool changes in hand-held drills or impact drivers with hex chucks. The 80 mm diameter gives a standard large opening suitable for many installation tasks while remaining compact enough for controlled handling.

Suitable for

• Creating circular holes in mild and stainless steel sheets
• HVAC ductwork openings and ventilation installations
• Routing holes for electrical conduits and junction boxes
• Plumbing and pipe penetration through metal panels

Key specifications

• Cutting diameter: 80 mm
• Tooth material: tungsten carbide (welded carbide teeth)
• Shank type: HEX (hexagonal)
• Intended materials: metal and other hard materials
• Application: hole saw for circular cuts

How to use

Mark the center of the hole and secure the workpiece to prevent movement. Fit the hole saw onto a compatible hex arbor or directly into a drill with a hex chuck, then set the drill to an appropriate speed for metal cutting. Apply steady, moderate pressure and allow the carbide teeth to cut without forcing; periodically withdraw to clear chips and cool the cutting edge. For thicker or harder metals use cutting lubricant to reduce heat and prolong tool life.

Usage recommendations

Use suitable personal protection such as safety glasses and gloves, clamp the workpiece firmly, and start drilling at a controlled speed. For best results on stainless steel and thick materials, use a cutting lubricant and avoid excessive feed rates to prevent overheating of the carbide teeth.
