Chicago-Latrobe 45632 1/2 Inch Drill Bit
The Chicago-Latrobe 45632 is a jobber length drill bit sized at 1/2 inch for general purpose drilling tasks. It is built from high speed steel with a black oxide finish for durability. The 135 degree split point design promotes accurate starts and reduces walking. This tool suits professionals and DIY users needing reliable hole making in metal and wood.
Decimal Equivalent .5000 and 135 Degree Point
The fractional 1/2 inch size matches a decimal equivalent of .5000 for precise specification. The heavy-duty construction handles demanding applications in steel and other hard materials. The split point geometry provides good centering without a centre punch. It runs out when used in extremely abrasive alloys or high-volume production without coolant.
High Speed Steel Construction and Black Oxide Finish
The high speed steel body resists heat buildup during normal drilling speeds. Black oxide coating adds lubricity and helps prevent chip welding on the cutting edges. No coolant holes are present so external lubrication is recommended for deep cuts. Power draw and vibration stay low in typical handheld or press operations.

Questions about this item
Will the 135° split point on this 1/2 in bit start cleanly in the same materials I currently drill with standard bits?
The 135° split point is designed to reduce walking and provide accurate starting in harder materials such as stainless steel and high-tensile alloys where standard points may struggle.
How can I verify the bit is performing correctly after I begin drilling?
A properly working bit will produce short, curled chips rather than long strings, the hole diameter will match the .5000 decimal equivalent, and the cutting edges will stay sharp without excessive heat buildup.
Does the box contain only the 45632 drill bit or are there additional accessories included?
The package contains the single 1/2 in jobber length drill bit made of high speed steel with black oxide finish; no coolant adapters, cases or extra bits are supplied.
