PRODUCT SPECIFICATION
MECHANIC'S HOLE SAW KIT
Benchmark Abrasives Mechanic's Hole Saw Kit brings together five commonly used bi-metal hole saw sizes for maintenance, automotive, fabrication, installation, and general repair work. Each hole saw uses shock-resistant and shatter-resistant bi-metal construction with cobalt-matrix high-speed steel cutting teeth laser-welded to a tough alloy-steel body for dependable cutting across wood, metal, plastic, and other supported materials.
The included hole saws feature 4/6 variable-pitch teeth with a positive rake angle for fast, clean cutting while helping reduce chatter. A 1-1/2" cutting depth handles common construction materials, and side cutouts make plug and debris removal easier after drilling. The kit also includes a mandrel and adapter and stores together in a convenient carrying case.

FEATURES
-
FIVE USEFUL HOLE SAW SIZES – Includes 7/8", 1", 1-1/8", 1-1/4", and 1-1/2" diameters for a versatile range of drilling applications.
-
SHATTER-RESISTANT & SHOCK-RESISTANT CONSTRUCTION – Tough bi-metal construction withstands the impact and vibration common in demanding hole-cutting work.
-
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 balance of cutting performance, strength, and flexibility.
-
4/6 VARIABLE-PITCH TEETH – Variable tooth spacing helps reduce chatter while promoting smoother, faster cutting.
-
POSITIVE RAKE ANGLE – Aggressive tooth geometry helps the cutting edge engage efficiently for quick, clean cuts.
-
1-1/2" CUTTING DEPTH – Provides useful cutting capacity for common construction and maintenance materials.
-
EASY PLUG REMOVAL – Side cutouts provide access for clearing chips, debris, and cut plugs after drilling.
-
MANDREL & ADAPTER INCLUDED – Kit contents include one mandrel and one adapter for setup flexibility.
-
CARRYING CASE INCLUDED – Keeps the hole saws and accessories organized together between jobs.
-
MADE IN USA – Hole saw kit is Made in USA.
KIT CONTENTS
The Mechanic's Hole Saw Kit includes:
- 7/8" Bi-Metal Hole Saw
- 1" Bi-Metal Hole Saw
- 1-1/8" Bi-Metal Hole Saw
- 1-1/4" Bi-Metal Hole Saw
- 1-1/2" Bi-Metal Hole Saw
- 1 Mandrel
- 1 Adapter
- Carrying Case
The published source identifies the mandrel and adapter as included kit components but does not publish their individual part numbers, shank sizes, or thread specifications.
APPLICATIONS & PERFORMANCE
Designed for clean, accurate hole cutting in materials such as:
- Wood and wood framing
- Plywood
- Sheet metal
- Ferrous metals
- Aluminum and other non-ferrous metals
- Wood composites
- Plastics
- Rubber
- Drywall and sheetrock
The five included diameters provide useful coverage for mechanical maintenance, automotive work, fabrication, equipment repair, electrical pass-throughs, general installation, and shop applications.
Cobalt-matrix high-speed steel cutting teeth provide wear resistance at the cutting edge, while the alloy-steel body adds toughness and flexibility. The 4/6 variable-pitch pattern balances cutting speed with smoother tooth engagement across different materials and thicknesses.
MACHINE COMPATIBILITY
Designed for use with compatible rotary drills and the appropriate hole saw mounting components.
COMPATIBLE EXAMPLES INCLUDE:
-
DEWALT® DCD991 and DCD996
-
Milwaukee® 2903-20, 2904-20 and 2807-20, 2410-20 and 2411-20
-
Makita® XPH14Z, XAD03Z and 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.
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.
- Confirm that the hole saw, mandrel, adapter, and pilot components are correctly assembled before use.
- Use rotary drilling mode only; do not use hammer action with a hole saw.
- Confirm the drill manufacturer's hole-saw capacity for the selected diameter and material.
- Use appropriate drilling speed and pressure for the material and hole size.
- 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.
- Stop the drill completely before clearing chips, removing cut plugs, or changing components.
- Do not use a damaged, cracked, excessively worn, bent, or distorted hole saw or mounting component.
