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

Milwaukee® 49-56-0243 HOLE DOZER™ 5" Bi-Metal Hole Saw – Technical Product Information

The Milwaukee® 49-56-0243 HOLE DOZER™ 5" Bi-Metal Hole Saw is engineered for professional contractors requiring precision, durability, and performance in heavy-duty cutting applications. Featuring a 3.5 TPI variable pitch tooth design, this hole saw provides faster cuts, longer service life, and reduced vibration in demanding environments. Constructed from Matrix II high-speed steel alloyed with 8% cobalt, it offers exceptional heat resistance and wear durability when cutting metals and composite materials. The reinforced alloy body ensures consistent concentricity and dimensional accuracy. Milwaukee’s ALL-ACCESS SLOT™ design enhances chip evacuation, simplifies plug removal, and provides superior pilot bit visibility for precise placement. The Thermoset Coating minimizes friction and heat buildup, improving efficiency and delivering up to 25% more holes per charge when used with cordless tools. Proudly manufactured in the USA, this professional-grade hole saw is built to perform across industrial, mechanical, and construction applications.
