Description

UNMATCHED DURABILITY WITH 8% COBALT ALLOY PERFORMANCE

Maximize your cutting efficiency with the Bosch HB150 1-1/2 Inch Bi-Metal Hole Saw. Designed to meet the rigorous demands of professional tradespeople, this hole saw features an enhanced bi-metal construction infused with 8% cobalt alloy (M42). This superior formulation provides exceptional heat resistance, allowing the cutting edge to stay sharp longer even in tough materials. Whether you are drilling through wood, mild steel, aluminum, or plastic, this accessory delivers reliable, clean cuts hole after hole.

Engineered for speed, the Bosch HB150 utilizes the innovative "Progressor" tooth design with a 5 TPI (Teeth Per Inch) pitch. This variable tooth geometry cuts faster and clears chips more effectively than standard designs. To handle the high torque of modern power drills, the cup is built with a reinforced shoulder that adds critical structural strength, preventing ovaling and breakage. Compatible with both standard and Quick Change™ mandrels (adapter AN02 required for Quick Change), this versatile tool is an essential addition to any toolbox.

Key Features

  • 8% Cobalt Alloy: M42 bi-metal construction resists high heat for extended cutting life in metal and wood.
  • Progressor Tooth Design: Variable 5 TPI geometry ensures faster cutting speeds and cleaner chip removal.
  • Reinforced Shoulder: Strengthened base prevents structural failure and ovaling under high torque.
  • Broad Compatibility: Works with standard mandrels and is compatible with Quick Change systems (adapter sold separately).
  • Deep Cut Capacity: Offers a cutting depth of approximately 1.6 inches for drilling through thick materials.
  • Versatile Application: Ideal for cutting wood, metal, plastic, and composite materials.

Pro-Tip: When cutting metal with this hole saw, start at a slow speed and use cutting oil. This helps keep the cobalt teeth cool and prevents the bit from overheating, which significantly extends the life of the accessory.
