MASTER ELECTRICIAN'S HOLE SAW KIT
Benchmark Abrasives Master Electrician's Hole Saw Kit combines eleven bi-metal hole saw sizes for electrical installation, conduit work, panel and junction-box openings, maintenance, fabrication, and general construction. 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, while side cutouts make plug and debris removal easier after drilling. The kit also includes three mandrels, a 12" extension, and a carrying case for organized storage and added reach when working in deeper or obstructed locations.

FEATURES
-
ELEVEN HOLE SAW SIZES – Covers a broad range from 7/8" through 4-1/2" for electrical, construction, maintenance, and fabrication work.
-
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 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 electrical and construction materials.
-
EASY PLUG REMOVAL – Side cutouts provide access for clearing chips, debris, and cut plugs after drilling.
-

The published source identifies the mandrels and extension as included kit components but does not publish the individual mandrel shank sizes, thread specifications, or component part numbers.
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 diameter range makes this kit well suited for electrical work including conduit routing, cable pass-throughs, panel and junction-box openings, service and maintenance work, fabrication, 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.
The included 12" extension provides additional reach where access is limited or the drilling location is recessed.
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
-
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, pilot components, and extension 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.
- Use extra control when operating with the 12" extension because added reach can increase leverage and runout.
- 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.
