4-3/4" Bi-Metal Hole Saw Bulk, Rip Guard 3.5 TPI

Milwaukee® 49-56-0237 HOLE DOZER™ 4-3/4" Bi-Metal Hole Saw – Technical Product Information

The Milwaukee® 49-56-0237 HOLE DOZER™ 4-3/4" Bi-Metal Hole Saw is designed for precision and longevity in professional drilling applications across metal, wood, and composite materials. Engineered with Milwaukee’s advanced 3.5 TPI variable pitch tooth geometry, it delivers exceptional cutting performance, faster penetration, and reduced vibration under load. The hole saw’s Matrix II high-speed steel teeth, alloyed with 8% cobalt, provide superior heat resistance and extended life in high-demand cutting environments. The reinforced alloy body maintains dimensional stability, while the ALL-ACCESS SLOT™ design ensures efficient plug removal, improved chip evacuation, and clear pilot visibility for precise alignment. The Thermoset Coating minimizes friction and heat generation, allowing for faster, cooler cuts and optimal cordless tool efficiency. Proudly manufactured in the USA, this hole saw meets professional standards for accuracy, endurance, and productivity in the field.
