15/16 inch cobalt drill bit with 118 degree point and reduced half-inch shank for heavy-duty drilling
The Chicago-Latrobe 53460 is a silver and deming drill bit designed for general-purpose metalworking tasks. It suits machinists and maintenance technicians who need a reliable cutting tool for drilling larger holes in various materials. The reduced shank allows compatibility with standard 1/2 inch drill chucks. This new accessory arrives ready for immediate workshop use.
The 15/16 inch drill bit size handles medium-to-large diameter hole requirements in steel, iron, and other ferrous metals. Its machining cobalt material provides hardness and heat resistance for extended tool life during repetitive drilling. The straw bronze finish helps identify the bit and offers some corrosion protection. Performance limits appear when drilling extremely hard alloys or very deep holes without adequate cooling.
The 118 degree point angle is the critical specification determining this bit's cutting behaviour and material suitability. This standard angle centres easily on flat surfaces and works well across a broad range of ferrous metals. It does not self-centre as aggressively as split-point designs on curved or hardened surfaces. Buyers needing faster penetration in stainless steel or precise starting on rounded stock should select a different point geometry.

Yes, the 53460 has a 1/2 reduced shank that fits standard 1/2 in chucks on older drill presses and handheld drills.
The 118 degree point should centre itself quickly in steel and produce even, straw-coloured chips without walking or excessive heat.
The bit ships as a single 15/16 in cobalt drill; no case, cutting fluid or additional accessories are included.
