MK Morse 2-3/8″ Shallow Carbide Tipped Hole Cutter 166324
The MK Morse 2-3/8″ Shallow Carbide Tipped Hole Cutter is a precision-engineered solution for high-speed, repeatable fabrication. Designed with a 3/16″ (4.5mm) cutting depth, it is optimized for creating clean, fast holes in sheet metal, electrical enclosures, stainless steel plate, aluminum, and composite materials. This is not a standard hole saw; it’s an integrated cutting system. The precision-ground triple-chip carbide teeth provide a smooth, clean cut, while the built-in ejector spring automatically clears the slug, eliminating the need to stop and pry it out. The step-center pilot bit ensures stable starts and reduces the violent “break-through” impact common with other cutters.
Features & Benefits
- Precision Ground Triple Chip Tooth: Delivers a clean, fast, and smooth cut with less burring.
- 3/16″ (4.5mm) Cutting Depth: Optimized for sheet metal and fabrication applications.
- Integrated Ejector Spring: Automatically removes the slug for faster productivity and no downtime.
- Step-Center Pilot Bit: Provides easy, accurate starting and reduces “break through” impact, enhancing safety and control.
- Grooved Gullet: Efficiently directs chips and swarf away from the cut.
- One-Piece System: Flat, 6-sided shank fits securely in 3/8″ and larger drill chucks without a separate arbor.
Applications
- Ideal for HVAC, Electrical, Plumbing, Construction, Automotive, and Boating/Marine professionals.
- Cuts sheet metal, stainless steel plate, angle iron, black iron pipe, aluminum, plastics, PVC/ABS, fiberboard, composites, and more.
