Cle-Line 18025 Drill Bit Application
The Cle-Line 18025 is a 29/64 inch jobber length drill bit built for heavy-duty work. It features a 135 degree split point made from HAWA high speed steel with a black and gold finish. The decimal equivalent is .4531 inch. This fractional inch bit is designed for general purpose drilling in metal and other tough materials.
Suitability for Drilling Tasks
This bit suits machinists and maintenance crews who need a durable fractional size for jobber length holes. The split point helps start the hole without a centre punch. Buyers who require coolant-through capability or a different point angle should look at other options. The non-coolant design limits use in deep hole or high heat applications.
Critical Specification Deciding Fit
The 29/64 inch fractional diameter with a 135 degree split point is the single specification that determines if this is the right part. The HAWA high speed steel material and black and gold finish support the heavy-duty rating. Match this exact size and point geometry to the hole requirement before purchasing.

Questions about this item
Which drill bit size should I pick for a 29/64 inch hole?
This bit is the 29/64 inch size with a decimal equivalent of .4531, so it matches that exact fractional diameter.
What does the 135 degree point angle do when drilling metal?
The 135 degree split point centres the bit quickly and reduces walking on hard surfaces, helping the cutting edges engage faster in steel.
How does the jobber length design affect reach and rigidity?
Jobber length gives a standard flute and overall length for general-purpose drilling, balancing reach and stiffness in a handheld drill or press.
