Chicago-Latrobe 55434 118 Degree 17/32 in Silver & Deming Drill 1/2 Reduced Shank

Chicago-Latrobe 55434 Drill Bit

The Chicago-Latrobe 55434 is a Silver & Deming drill bit built for general-purpose drilling in metal and wood. Its 118-degree point angle centres the bit quickly and reduces walking on flat surfaces. The 1/2-inch reduced shank allows the bit to fit standard drill chucks while delivering a larger 17/32-inch cutting diameter. This accessory suits maintenance technicians and workshop users who need a single bit for oversize holes.

17/32-Inch Cutting Diameter

The 17/32-inch drill bit size is the critical dimension that determines whether this bit matches the required hole specification. A 118-degree point angle supports efficient chip evacuation in mild steel, aluminium and timber. High-speed steel construction with a black oxide finish adds wear resistance and helps retain cutting lubricant during operation. Verify the exact fractional size against your drawing before ordering.

Fits Standard 1/2-Inch Chucks

The reduced shank design lets the bit mount securely in any drill or press equipped with a 1/2-inch capacity chuck, eliminating the need for a larger spindle. High-speed steel material handles moderate feed rates and speeds common in handheld and bench-top machines. Black oxide surface treatment reduces friction and resists corrosion in damp shop environments. Ensure the workpiece is clamped rigidly to prevent bit deflection.
