PRODUCT SPECIFICATION
INDUSTRIAL MAINTENANCE HOLE SAW KIT
Benchmark Abrasives Industrial Maintenance Hole Saw Kit brings together eleven bi-metal hole saw sizes for plant maintenance, fabrication, repair, installation, electrical, plumbing, and general industrial 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 and maintenance materials, while side cutouts make plug and debris removal easier after drilling. The kit also includes two mandrels and a carrying case to keep the full assortment organized and ready for shop or field use.

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 broad size range makes this kit well suited for industrial maintenance departments, fabrication shops, equipment repair, facility installation, electrical work, plumbing, mechanical service, and general construction.
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 included mounting components.
COMPATIBLE EXAMPLES INCLUDE:
-
DEWALT® DCD991 and DCD996
-
MILWAUKEE® 2903-20, 2904-20 and 2807-20, 2410-20 and 2411-20
-

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, 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.
