Cle-Line C21107 13PC Cobalt Drill Set
The Cle-Line C21107 is a 13-piece jobber length drill bit set manufactured from cobalt steel with a straw bronze finish. It is designed for mechanics and metalworkers who need durable bits for drilling hard materials such as stainless steel or cast iron.
Suits users drilling tough alloys.
This set suits professionals and serious DIYers who regularly drill high-tensile alloys and want the heat resistance of cobalt. It is not intended for woodworkers or general-purpose users who only drill soft materials and would gain no benefit from the specialised construction.
135-degree point angle for self-centering starts
The 135-degree point angle allows the bits to self-center and begin cutting immediately without a centre punch. This geometry reduces wandering on hard surfaces and is the key specification that determines suitability for precision metal drilling tasks.

- 13 cobalt drill bits for high-heat metal cutting

Questions about this item
What does the 135-degree point angle do when the bit is in a drill?
The 135-degree point angle reduces walking on hard materials and starts holes faster with less pressure than standard points.
What shank style do these cobalt jobber bits use?
These bits have straight round shanks that fit standard three-jaw drill chucks up to the largest bit diameter in the set.
How long are the jobber-length bits in this 13-piece set?
Jobber-length bits follow standard length-to-diameter proportions so each bit in the set reaches the typical flute and overall length for its size.
