Milwaukee Thunderbolt 1/4″ Hole Saw Pilot Bit 49-56-8031

REINFORCED CORE GEOMETRY FOR HIGH-TORQUE HOLE SAW APPLICATIONS

The mechanical failure of standard pilot bits often stems from side-load stress during aggressive hole saw engagement. The Milwaukee Thunderbolt pilot bit addresses this with a significantly thicker core, utilizing a tapered web that provides structural rigidity where standard bits typically snap. The 135 split point is a critical engineering feature for precision, ensuring the bit bites immediately without walkinga necessity when working on curved surfaces or dense materials. By incorporating a parabolic flute, this bit optimizes chip evacuation, reducing friction-induced heat and extending the service life of the cutting edge for a higher professional ROI.

• / Thunderbolt Tapered Web provides a thicker core for maximum protection against side-load breakage during heavy-duty drilling.
• / 135 Split Point starts on contact to prevent walking and ensure precise hole placement without the need for a center punch.
• / Parabolic Flute design clears chips and debris rapidly to keep the bit cool and maintain cutting efficiency.
• / 3-Flat Shank eliminates slipping in the hole saw arbor or drill chuck for consistent power transfer.
