3-5/8" Bi-Metal Hole Saw Bulk, Rip Guard 3.5 TPI

Milwaukee® 49-56-0197 HOLE DOZER™ 3-5/8" Bi-Metal Hole Saw – Technical Product Information

The Milwaukee® 49-56-0197 HOLE DOZER™ 3-5/8" Bi-Metal Hole Saw is designed for professional contractors who require a precision-engineered cutting tool capable of withstanding heavy use in demanding applications. Utilizing an advanced 3.5 TPI variable pitch tooth design, this hole saw achieves superior cutting speed and extended life when drilling through metals, wood, and composite materials. Constructed with Matrix II high-speed steel teeth alloyed with 8% cobalt, it delivers exceptional heat resistance and wear durability. The reinforced alloy steel body ensures dimensional stability and accurate hole geometry. Milwaukee’s proprietary ALL-ACCESS SLOT™ system simplifies plug removal, enhances chip evacuation, and provides improved visibility of the pilot bit for precise placement. A Thermoset Coating reduces friction, minimizes heat buildup, and allows up to 25% more holes per battery charge when used with cordless equipment. Proudly made in the USA, the HOLE DOZER™ line sets the benchmark for industrial-grade cutting reliability.
