135° Split Point Jobber Drill
Cle-Line 18004 is a heavy-duty jobber length drill bit made from high speed steel with a black and gold finish. The 135 degree split point design starts on contact and reduces walking on hard surfaces. It suits general purpose drilling in metal, wood and plastic for trade and maintenance work.
Trade users needing fast starts on steel
Mechanics and fabricators who want a self-centering point on a standard length bit will benefit from the split point geometry. Buyers who need coolant-fed drilling or a reduced shank for larger chucks should look at alternative designs. The bit has no coolant holes and a straight shank only.
1/8 inch fractional diameter
The drill bit size is 1/8 inch with a decimal equivalent of .1250, fitting any chuck that accepts this diameter. This single dimension determines whether the bit matches the hole required for the job. Verify the target hole size before purchase.

Questions about this item
Will a 1/4-inch chuck hold the 1/8-inch shank of this 135° jobber bit securely?
Yes, the 1/8-inch shank fits any standard 1/4-inch or 3/8-inch drill chuck without an adapter.
Can I run this high-speed steel bit at the same RPM I used for my older carbon-steel bits?
High-speed steel tolerates higher cutting speeds, so you can maintain or increase RPM compared with carbon-steel bits.
How do I confirm the 135° split point is cutting correctly after the first hole?
The split point should self-centre without a centre punch and produce short, curled chips rather than long strings.
