Chicago-latrobe 47226 Jobber Length Drill Bit 1.15mm Hss

Product Description

The CHICAGO-LATROBE 47226 is a jobber length twist drill bit designed for general-purpose drilling in cast iron and steel. Built from high speed steel (HSS) with an oxide finish, the bit measures 1.15 mm (0.0453 inches) in diameter with an overall length of 36 mm (1.417 inches). The 118-degree standard point angle and web-thinned, tapered web geometry reduce entry force and help maintain accurate starts on metal workpieces. A right-hand spiral flute with regular helix efficiently clears chips during through-hole and blind-hole operations. This bit is sold individually and meets DIN 338 standards.

The 47226 is suited for production and maintenance drilling in ferrous materials including cast iron and steel. Its straight-cylindrical shank fits standard drill chucks found on benchtop drill presses, hand drills, and CNC machines. The 14 mm (0.551 inch) flute length accommodates typical hole depths expected of jobber-length tooling. Machinists, maintenance technicians, and fabricators working with light ferrous stock will find this bit a reliable general-purpose option in Series 150.

Key Features

• High speed steel construction with oxide coating for corrosion resistance and reduced friction
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust force
• Right-hand cut, regular spiral flute for efficient chip evacuation in ferrous materials
• Straight-cylindrical shank (0.0453 inches diameter) fits standard drill chucks without adapters
• Meets DIN 338 specification for jobber length drill bits
• General-purpose grade suitable for cast iron and steel workpieces

Compatibility

Designed for use in standard drill chucks on hand drills, drill presses, and CNC drilling equipment. Primary workpiece materials are cast iron and steel. Diameter tolerance of -0.0005 to 0.0000 inches ensures consistent fit for general-purpose hole-making applications.

Installation Notes

Secure the straight-cylindrical shank firmly in the drill chuck and verify concentricity before starting. Always wear appropriate eye protection when drilling metal. Secure the workpiece with a vise or clamp — never hold it by hand during drilling. Apply cutting fluid when drilling steel to extend tool life and improve hole finish.
