Built Tough Pro Grade Annular Cutter And Mag Drill Bit, 5/8 Inch Hole Size, 3/4 Inch Weldon Shank, Fully Ground High Speed Steel, 1 Inch Cut Depth, 2 Pack Slides Right On Magnetic Drills, Gets The Job Done
✔️ 5/8 dia hole, 1 in cut depth, 3/4 weldon shank, 2 pack
These professional magnetic drill bits are engineered for heavy duty metal fabrication and industrial maintenance tasks. Each two pack unit pairs a robust annular cutter with a precise pilot pin to deliver accurate round holes in steel plate, beam flanges, and structural frameworks without requiring extra setup time.
✅ CNC machined M20AL high speed steel body resists heat and wear ✅ 3/4 inch twenty flat weldon shank locks securely into mag drills ✅ 5/8 inch cutting diameter punches through up to one inch thick metal ✅ Includes dedicated plastic storage housing and exact one quarter by three inch guide pin💡 How do modern annular cutter tools deliver clean holes on thick structural steel These pro grade step drill bits are pretty handy for stripping material efficiently when paired with a compatible power head and stable mounting base. - Machined m20al steel retains cutting edge hardness while resisting thermal expansion during aggressive feed cycles. - Precision honed clearance angles reduce friction and pull clear chips to prevent bind up in heavy gauge metals. - Steady axial thrust combines with the magnetic anchor to keep the pilot guide centered until the full bore is punched.
