The CHICAGO-LATROBE 44312 is a jobber length drill bit designed for general-purpose drilling in non-ferrous metals and similar materials. Part of the Series 150D lineup, it is sized to wire gauge 42, which equals 0.0935 inches in decimal. The bit features a standard 118-degree split point with web thinning for improved centering and reduced thrust on entry. A bright, uncoated high speed steel construction keeps the profile simple and cost-effective for everyday shop and field use. With an overall length of 2.25 inches and a spiral flute design, this bit suits hand-held drills, drill presses, and CNC setups requiring a straight-cylindrical shank. Licensed tradespeople and machinists working on light fabrication and mechanical assembly reach for this style regularly.
This bit is built for general-purpose drilling in non-ferrous metals such as aluminum, brass, and copper, as well as plastics and similar softer workpiece materials. The 1.25-inch flute length provides adequate chip evacuation for through-hole work in thin stock. The right-hand cut and regular spiral geometry make it a standard fit for conventional drill presses and handheld power drills. It conforms to DIN 338 standards, making it a reliable option in both production and maintenance-repair-operations environments where consistent sizing and geometry are expected.
Designed as an OEM-style general-purpose jobber length drill bit for use in standard drill chucks accepting a 0.0935-inch straight-cylindrical shank.
Installation is performed by machinists, tool and die technicians, and maintenance tradespeople using standard drill presses, CNC drilling machines, or handheld power drills with a keyed or keyless chuck. Always secure the workpiece before drilling and confirm the chuck is fully tightened before starting the spindle. Inspect the cutting edges for wear or chipping before each use, and replace the bit if the point is dull or the flutes are damaged to avoid oversized holes or workpiece damage.
