Chicago-Latrobe 46699 Cobalt Jobber Drill Bit
This Chicago-Latrobe 46699 is a new jobber-length drill bit made from cobalt steel. It carries a 135 degree split-point tip and a straw-bronze surface finish. The bit is designated wire-gauge size 29 with a decimal equivalent of .1360 inches.
Suited for drilling hard metals
The cobalt construction and 135 degree split point suit maintenance and production drilling in stainless steel, titanium and other tough materials. The split point reduces walking on hard surfaces. Buyers who need a coolant-through design or a different point angle should look at something else.
135 degree split-point geometry
The 135 degree split-point geometry is the specification that determines whether this bit matches the application. It centres quickly without a centre punch and performs best in materials that demand a sharp, self-centring point.

Questions about this item
Will the #29 shank fit a standard 3/8 in drill chuck?
The #29 jobber bit has a 0.1360 in diameter shank, so it fits any chuck that accepts 3/8 in or larger capacity.
How do I start a hole with the 135° split point without the bit walking?
Apply light pressure and let the self-centring split point engage the metal before increasing feed; the 135° angle reduces wandering on hard materials.
When should I replace this cobalt bit?
Replace the bit when the cutting lips show visible rounding or the straw/bronze surface colour wears away, indicating the cobalt edge is dull.
