13-Piece Cobalt Drill Bit Set

This Klein Tools set contains 13 jobber-length bits ranging from 1/16 to 1/4 inch. Made from M35 high-speed steel with 5% cobalt, they target professionals and DIY users who drill stainless steel, metal, wood and plastic. The cobalt alloy increases heat and wear resistance for longer tool life.

135° Split Point Installation

The 135-degree split point centers itself on contact and reduces walking, so bits start cleanly without a centre punch. Chips clear quickly through the flutes, lowering friction and heat during drilling. A plastic storage case keeps the 13 pieces organised and protected between jobs.

M35 Cobalt Capacity Range

The set covers fractional sizes from 1/16 through 1/4 inch, handling common sheet-metal, hardware and woodworking holes. Bits larger than 1/4 inch or specialised materials such as hardened steel, masonry or glass fall outside this range. Users needing wider diameters or different substrates will require additional sets.

Questions about this item

How can I confirm the 135° split point is centering properly after I start drilling?

The split point should self-centre on contact and produce a clean hole without the bit wandering across the workpiece.

What sizes are included in the 13-piece set and does the plastic case come with it?

The set contains 1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 11/64, 3/16, 13/64, 7/32, 15/64 and 1/4 inch bits in a plastic storage case.

Why choose the M35 cobalt alloy over the 4241 high-speed steel option?

M35 contains 5% cobalt for higher heat, wear and chip resistance, giving longer tool life than 4241 HSS bits.
