Total TAC101303 HSS drill bit 13mm 5pcs

5-Piece Maximum-Capacity Pack: Includes five identical 13.0 mm bits—the maximum standard size for standard 1/2-inch drill chucks—ideal for M12/M13 heavy bolt hole drilling and heavy metal fabrication.

135° Split Point Tip: Self-centering split point prevents bit “walking” on polished or curved metal surfaces, delivering precise hole starts without requiring a center punch.

High-Volume Spiral Flutes: Deep, polished flutes quickly eject large metal shavings and swarf to manage heat buildup and extend cutting edge life.

Standard Round Shank: Fits all standard 13 mm (1/2-inch) 3-jaw keyed or keyless drill chucks on corded drills, heavy-duty cordless driver-drills, and drill presses.
