Cleveland 4.00 mm Cobalt Jobber Drill

This cobalt jobber drill bit measures 4.00 mm with a 135 degree split point and TiN coating. It is designed for general-purpose drilling in metal where a standard length and metric sizing are required. The split point helps reduce walking on hard surfaces.

Upgrade from standard HSS bits when drilling

The cobalt construction and TiN finish extend edge life compared with uncoated high-speed steel in stainless and high-strength steels. The jump is worthwhile when hole quality and bit longevity matter more than lowest cost. Buyers who need coolant-through capability or a different point geometry should look elsewhere.

Questions about this item

What shank diameter and length does the 4.00 mm jobber drill need to fit my drill chuck?

The bit has a 4.00 mm diameter shank and standard jobber length, so it fits any three-jaw chuck that accepts 4 mm round shanks.

How do I start the hole correctly with the 135° split-point tip?

Apply light pressure and let the self-centring split point bite at the marked centre; do not use a centre punch or the tip can chip.
