Chicago-Latrobe 52437 37/64 in 118 Degree Silver & Deming Drill

Precision drilling for large holes

The Chicago-Latrobe 52437 is a Silver & Deming drill bit designed for creating 37/64 inch holes in metal. Its high-speed steel construction withstands the heat generated when boring large diameters. The 118-degree point angle provides reliable centring and chip ejection in general-purpose machining. This accessory targets machinists and maintenance technicians who need consistent results in ferrous and non-ferrous materials.

Fits standard half-inch chucks

The reduced 1/2 inch shank allows the bit to be secured in any drill press or heavy-duty hand drill equipped with a standard 1/2 inch capacity chuck. This eliminates the need for a larger specialised holder or a Morse taper adapter. The black oxide finish reduces friction and resists corrosion during extended cutting cycles. The design frees up larger machine capacity for other tooling.

Black oxide finish extends service life

The factory-applied black oxide coating improves lubricity and helps prevent workpiece material from welding to the cutting edges. This surface treatment also adds a layer of corrosion resistance during storage. No additional coatings or specialised lubricants are supplied with the bit. Users should apply appropriate cutting fluid for the specific material being drilled to maximise tool life.
