Product Description
The CMT Bi-Metal Plus Hole Saw - 2-9/16" (65mm) is a professional-grade cutting tool engineered for demanding hole-cutting tasks in metal, steel, cast iron, aluminum, copper, brass, and plastics. Built with an 8% Cobalt bi-metal (BIM) construction, this 65mm hole saw delivers extended cutting life and consistent performance on tough materials where standard hole saws fall short. Designed for right-hand rotation and compatible with hexagonal shank arbors, it is a reliable choice for contractors, electricians, plumbers, and fabricators who need accurate, clean holes in a wide range of substrates.
Key Features
- Bi-Metal 8% Cobalt (BIM) Construction - the 8% Cobalt content in the bi-metal teeth significantly extends cutting life compared to standard bi-metal hole saws, reducing tool changes and downtime on the job site.
- 2-9/16" (65mm) Cutting Diameter - a precisely sized 65mm cut opening suits a broad range of trade applications including conduit, pipe, and fixture rough-ins that require an accurate, repeatable hole size.
- 45mm Cutting Depth - the generous 45mm depth of cut allows the saw to bore through thick workpieces, wall assemblies, and layered materials in a single pass without repositioning.
- Right-Hand Rotation - engineered for standard right-hand rotation, ensuring full compatibility with conventional cordless drills, corded drills, and drill presses without requiring reverse settings.
- Hexagonal Shank Interface - the hexagonal shank design provides a secure, slip-resistant connection to compatible arbors, reducing torque loss and keeping the saw centered during aggressive cuts.
- Bi-Metal Material Versatility - the BIM composition allows the saw to transition between ferrous and non-ferrous materials as well as plastics, making it a versatile single-tool solution across multiple material types.
Why This Product
- The 8% Cobalt bi-metal construction addresses one of the most common frustrations with hole saws - premature tooth wear - by delivering a longer usable cutting life on stainless steel, cast iron, and hardened steel without requiring a specialty tool for each material.
- At 45mm cutting depth, this hole saw handles real-world material thicknesses that shallower saws cannot clear in one pass, saving time and reducing the risk of a stuck or stalled saw mid-cut.
- The hexagonal shank connection reduces cam-out and slippage during high-torque cuts in hard metals, giving the operator better control and a cleaner finished hole.
- With right-hand rotation compatible with standard drills and drill presses, this hole saw integrates immediately into existing tool setups without requiring specialized equipment or adapters beyond a compatible hexagonal arbor.

Frequently Asked Questions
What materials can the CMT Bi-Metal Plus 2-9/16" Hole Saw cut through?
The BIM 8% Cobalt construction allows this hole saw to cut through stainless steel, steel, cast iron, aluminum, copper, brass, and plastics. The bi-metal composition makes it suitable for both ferrous and non-ferrous metals as well as plastic materials in a single tool.
What is the cutting depth of this 65mm hole saw?
This hole saw provides a cutting depth of 45mm, which is sufficient for boring through thick workpieces, multi-layer assemblies, and standard wall constructions in a single pass.
What type of shank does the CMT 551-065X use?
The 551-065X uses a hexagonal shank interface. This shank style provides a secure, torque-resistant connection to compatible hexagonal arbors, reducing slippage during heavy-duty cuts in hard metals.
Is this hole saw compatible with standard drills?
Yes. The right-hand rotation design and hexagonal shank are compatible with standard cordless drills, corded drills, and drill presses that accept a hex arbor. No reverse-rotation or specialty equipment is required for normal operation.
