13-Piece Cobalt Steel Drill Bit Set
The 13-piece cobalt steel drill bit set covers fractional sizes from 1/16 inch through 1/4 inch in 64th increments. It is designed for drilling stainless steel, hard steels, wood and plastic. The 135-degree split point provides fast penetration and accurate self-centering. The cobalt construction retains hardness at elevated temperatures.
Installation and common issues
Bits install directly into any standard drill chuck that accepts the shank diameter. The precision-ground flutes and gold finish reduce friction, but cobalt steel is more brittle than high-speed steel. Excessive side pressure or high RPM without coolant can cause premature breakage in hard metals. The hinged metal index case keeps bits organised and visible during job changes.
Check your setup before ordering
Verify that your drill chuck capacity accommodates the 1/4-inch maximum shank size included in the set. Confirm the materials you intend to drill match the rated capability for stainless steel, hard steels, wood and plastic. Ensure you have cutting fluid or lubricant available for metal applications to maintain bit life and performance.

Questions about this item
How can I verify the 135 split point is centering correctly after I start drilling?
The 135 split point should bite instantly without wandering; a clean, centred hole in stainless or hard steel confirms it is working as intended.
Does the set include the metal case shown in the pictures or must I buy a case separately?
The 13-piece set ships in a sturdy hinged metal index case with sizes marked on the case; no separate case purchase is needed.
Which version of the 04190 should I choose if I need the full 1/16" to 1/4" range?
The 04190 model supplies the complete 1/16" through 1/4" by 64ths range in one 13-piece set; there are no alternative capacities to select.
