Hole saw M.K. Morse 32 mm bi-metal, 1 - 1/4" depth (MORSE-PTA-MHS20)

Bi-metal hole saw by M.K. Morse with a 32 mm cutting diameter and 1 - 1/4" cutting depth, designed for creating clean circular holes in metal and mixed materials. The bi-metal construction combines a flexible backing with high-speed steel teeth to provide wear resistance while retaining toughness. This hole saw is intended for use with compatible arbors and drill drivers and is suitable for installers and maintenance professionals working on pipes, panels and enclosures.

Advantages

The bi-metal design offers a balance of durability and toughness: high-speed steel teeth resist heat and retain sharpness, while the flexible backing reduces the risk of breakage. The 32 mm diameter and 1 - 1/4" cutting depth accommodate common conduit and pipe applications, and the saw produces clean, accurate holes with reduced burring. The construction is suitable for repeated use on a variety of materials, improving efficiency on the job.

Suitable for

• Cutting circular holes in metal sheets and panels
• Drilling apertures in pipes and conduits for cable routing
• Creating openings in enclosures and junction boxes
• Mixed-material tasks where both metal and softer substrates are present

Key specifications

• Cutting diameter: 32 mm
• Cutting depth: 1 - 1/4" (approx. 31.75 mm)
• Material: bi-metal construction with high-speed steel teeth and flexible backing
• Recommended use: metal and mixed-material cutting
• Compatibility: for use with appropriate arbors and drill drivers

How to use

Secure the appropriate arbor to the hole saw and mount the assembly to a compatible drill driver. Mark the centre point of the hole, position the pilot bit or arbor against the mark, and start drilling at low speed to establish the cut. Apply steady, moderate pressure and increase speed as the cut progresses, clearing chips periodically to avoid overheating. After cutting, remove burrs from the hole edges if necessary and inspect the workpiece for a clean finish.

Usage recommendations

Use cutting lubricant when working with harder metals to extend blade life and reduce heat. Match the drill speed and feed rate to the material being cut, and ensure the arbor and pilot bit are securely fitted to avoid wobble. Wear appropriate personal protective equipment, including eye protection and gloves, when operating power tools.
