Product Specification
9/16" BI-METAL HOLE SAW
Benchmark Abrasives 9/16" Bi-Metal Hole Saw is built for fast, clean hole cutting across wood, metal, plastic, and other common construction materials. Its shock-resistant and shatter-resistant bi-metal construction combines cobalt-matrix high-speed steel cutting teeth with a tough alloy-steel body for the durability needed in demanding drilling applications.
The 4/6 variable-pitch tooth pattern and positive rake angle help the saw cut efficiently while reducing chatter and producing cleaner holes. A 1-1/2" cutting depth gives it the reach needed for applications including wood framing, plywood, sheet metal, aluminum, plastics, and similar materials, while side cutouts make plug and debris removal easier after the cut.

Features
-
Shatter-Resistant & Shock-Resistant Construction – Tough bi-metal construction withstands the impact and vibration common in demanding hole-cutting applications.
-
Cobalt-Matrix High-Speed Steel Teeth – Durable cutting teeth provide strong wear resistance across wood, ferrous metals, aluminum, plastics, and other supported materials.
-
Laser-Welded Bi-Metal Design – High-speed steel cutting teeth are laser-welded to the alloy-steel body for a combination of cutting performance, strength, and flexibility.
-
4/6 Variable-Pitch Teeth – Variable tooth spacing helps reduce chatter while promoting faster, smoother cutting through different material types and thicknesses.
-
Positive Rake Angle – Aggressive tooth geometry helps the cutting edge engage efficiently for quick, clean cuts.
-
1-1/2" Cutting Depth – Provides the depth needed for common construction materials, including standard 2" x 4" lumber.
-
Easy Plug Removal – Side cutouts provide convenient access for clearing chips, debris, and the cut plug after drilling.
-
Made in USA – Manufactured in the United States for professional cutting applications.
Applications & Performance
Designed for cutting clean, accurate holes in:
- Wood and wood framing
- 2" x 4" lumber
- Plywood
- Sheet metal
- Ferrous metals
- Aluminum and other non-ferrous metals
- Wood composites
- Plastics
- Rubber
- Drywall and sheetrock
The cobalt-matrix high-speed steel cutting edge provides wear resistance at the teeth, while the alloy-steel body adds toughness and flexibility to help resist cracking and impact damage. The variable 4/6 TPI pattern balances cutting speed with smoother engagement across different material thicknesses.
Side cutouts in the hole saw body provide access for easier removal of chips, debris, and the cut plug after drilling.
Machine Compatibility
Designed for use with compatible rotary drills and a correctly sized Benchmark Abrasives hole saw arbor.
Compatible examples include:
-
DEWALT® models DCD991 and DCD996
-
Milwaukee® models 2903-20, 2904-20, 2603-20, 2604-20, 2410-20, 2411-20 and 2807-20
-
Makita® models XPH14 / XPH14Z, XAD03 / XAD03Z and XAD05 / XAD05Z
Use the correct arbor for the saw, match its shank to the drill chuck, and choose a drill suited to the hole diameter and material. Operate in rotary mode with hammer action off. For Milwaukee 2410-20/2411-20, choose the 1/4" or 3/8" shank arbor.
Compatible Benchmark Hole Saw Arbors
This 9/16" hole saw uses a 1/2"-20 thread.
Compatible Benchmark Abrasives arbor options include:
- 1/4" Hex Shank, 1/2"-20 Thread Hole Saw Arbor with Pilot Drill — BM-HSA5_1
- 3/8" Hex Shank, 1/2"-20 Thread Hole Saw Arbor with Pilot Drill — BM-HSA3_1
- 7/16" Hex Shank, 1/2"-20 Thread Hole Saw Arbor with Pilot Drill — BM-HSA4_1
Use the correct arbor for the saw, match its shank to the drill chuck, and choose a drill suited to the hole diameter and material. Operate in rotary mode with hammer action off. For Milwaukee 2410-20/2411-20, choose the 1/4” or 3/8” shank arbor.
Safety Tips
- Wear eye protection and appropriate hearing and respiratory protection. Keep hands, gloves and loose clothing clear of rotating parts.
- Secure the workpiece before drilling.
- Use rotary drilling mode only; do not use hammer mode with a hole saw.
- Confirm that the arbor, pilot drill, and hole saw are properly assembled and tightened before operation.
- Use the correct arbor thread and a shank size that fits the drill chuck.
- Use appropriate drilling speed and pressure for the material and hole diameter.
- Reduce pressure as the hole saw approaches breakthrough to help prevent grabbing.
- Allow the tool and workpiece to cool when cutting metal; use cutting fluid when appropriate for the material and application.
- Stop the drill and disconnect power or remove the battery before clearing chips or the cut plug.
- Do not use a damaged, cracked, excessively worn, or distorted hole saw.
