SALI Concrete Hole Saw

SALI Concrete Hole Saw

Feature：

1.High-strength tungsten steel material
Made of tungsten steel and alloy with high-frequency welding technology. Welded joints are smooth and strong, ensuring long-term durability under heavy-duty use.

2.Large cutting diameter
Cutting diameter of 105 mm (4-1/8 inches), capable of drilling large holes for air conditioning ducts, range hood exhaust pipes, sewer pipelines, etc.

3.SDS-Plus quick-change shank
Standard SDS-Plus shank design, compatible with most major brands of rotary hammers for fast installation and efficient power transmission.

4.Sharp triple-edged teeth
Thicker and sharper than ordinary blades. The triple-edged teeth can easily cut through steel bars up to 6 mm in diameter, providing faster drilling speed.

5.Spiral chip evacuation design
Features spiral flutes and dedicated chip removal holes to smoothly guide debris outward, preventing clogging and maintaining stable drilling.

6.Precise positioning system
Includes a pilot center drill bit and fixing screw. The cross-positioning design ensures balanced, stable operation and prevents deviation.

7.Corrosion-resistant robust construction
Main body made of 5140 steel with anti-corrosion treatment, suitable for long-term storage and use in outdoor or humid environments.

8.Application scope
Suitable for concrete, brick walls, masonry blocks, foam walls, mixed brick walls, fiber cement board, drywall, backer board, stucco, and plasterboard. Not for marble, pebbles, or large aggregates; avoid large-diameter rebar.

9.Usage Tips

Installation steps: Insert pilot drill → tighten fixing screw → screw on hole saw firmly.

Start at low speed – high initial speed may break the teeth.

When drilling hard materials (e.g., concrete), use flowing water for cooling to reduce wear.

Choose correct rotary hammer current: 7A–9A for ≤100mm; 9A–13A for >100mm.
