Osg 233-4062 Solid Carbide Jobber Drill 13/32 in

Product Description

The OSG 233-4062 is a solid carbide jobber-length drill bit designed for precision hole-making in ferrous metals and cast iron. It features a 150-degree web-thinned point that promotes self-centering entry and reduces thrust load at the cut. Three right-hand spiral flutes with a regular helix evacuate chips efficiently throughout the full flute length of 2.875 inches. The bright uncoated finish suits applications where coating compatibility is a concern or where the substrate finish must be preserved. This drill is sized at 13/32 inches (0.4062 inches) in diameter with a 4.5-inch overall length, and it belongs to the OSG Series 233 general-purpose carbide drill line used by machinists and tool-room professionals.

This drill is suited for production and job-shop drilling in steel and cast iron workpieces. Typical applications include blind holes, cross holes, standard through-drilling, and self-centering operations where a pilot drill is not required. The web-thinned point geometry makes it a practical choice for CNC machining centers and manual drill presses alike where repeatability and tool life in hard materials are priorities. It is sold individually and is intended for professional metalworking environments.

Key Features

• Solid carbide construction for extended tool life in steel and cast iron
• 150-degree web-thinned point promotes self-centering and reduces entry thrust
• Three-flute right-hand spiral design improves chip evacuation over two-flute alternatives
• Bright uncoated finish compatible with a wide range of cutting fluids and workpiece materials
• Straight cylindrical shank fits standard drill chucks and collet holders sized for 13/32 inches
• General-purpose Series 233 classification suitable for blind holes, cross holes, and through-drilling

Compatibility

Designed for drilling steel and cast iron workpieces (primary workpiece material codes P and K). Fits standard drill chucks and collet systems accepting a 0.4063-inch straight cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or tooling professionals familiar with carbide drill handling. Carbide is brittle and requires secure, runout-free chuck or collet clamping to prevent chipping at the cutting edge. Always verify spindle speed and feed rate settings are appropriate for the workpiece material and drill diameter before cutting. Inspect the cutting edge for chipping or wear before each use and remove from service if damage is observed.
