M2 High Speed Steel Double Ended Drill Bits, Number Sizes

High Speed Steel in Number sizes.

M2 High Speed Steel Double ended drill bits are versatile tools that have cutting edges on both ends, allowing them to perform multiple drilling tasks without the need for frequent bit changes.

With a double-ended drill bit, you essentially get two drill bits in one.

135° split point works to keep drill bits centered and fast cutting.

Sold in packs of 12 in sizes #10, #11, #20 and #30.

Applications

Great for roofing work, automotive body work, industrial, automotive, carpentry work and drilling pilot holes.

  • Roofing work: two cutting ends per bit keep you drilling on the roof instead of climbing down for a new bit.
  • Automotive body work: short 1/4″ flute length for control in sheet metal and panels.
  • Industrial and automotive: M2 high speed steel for everyday shop drilling.
  • Carpentry work: clean, centered holes with the 135° split point.
  • Drilling pilot holes: exact number sizes for pilot and clearance holes.

Why Double Ended

When one end dulls, flip the bit and keep going. Two cutting ends per bit means fewer bit changes and less downtime, and a pack of 12 gives you 24 cutting ends.
