Professional Drilling Accessory
The Chicago-Latrobe 55432 is a high-speed steel drill bit designed for general-purpose machining tasks. Its 118-degree point angle provides reliable starting performance across common materials. This accessory suits technicians and tradespeople who need a durable cutting tool for standard workshop applications. The black oxide finish helps resist wear during repeated use.
Reduced Shank Compatibility
A 1/2 inch reduced shank allows this bit to fit securely in standard drill chucks with smaller capacity. This design expands the range of compatible power tools without requiring a larger chuck or specialised collet. Users can deploy the bit on widely available corded or cordless drills, freeing up heavier equipment for other jobs. The shank geometry ensures stable torque transfer during operation.
Sustained Cutting Performance
High-speed steel construction maintains hardness at elevated temperatures generated during prolonged drilling cycles. The 118-degree point geometry distributes cutting forces evenly, reducing the tendency to wander or overheat in deep holes. Black oxide surface treatment lowers friction and aids chip evacuation when feed rates are kept steady. Consistent coolant or lubricant use further extends tool life under continuous load.

Questions about this item
How does the 118-degree point angle affect wear during continuous drilling?
The 118-degree point angle is a general-purpose geometry that centres quickly in steel, but under sustained heavy feed it generates more heat at the cutting lips than a split-point design, so cutting fluid and regular resharpening become the practical limits.
What heat or noise should I expect when running this bit all day in a drill press?
High-speed steel with a black-oxide finish conducts heat into the shank, so the bit and chuck will become hot to the touch; the drill press motor and spindle bearings produce the dominant noise, not the bit itself.
What chuck capacity must my drill already have to accept the 1/2 reduced shank?
Your drill chuck must open to at least 1/2 inch to grip the reduced shank; a 3/8-inch chuck will not hold this bit.
