Osg 570009311 Screw Machine Drill Bit 3/32 Inch Carbide

Product Description

The OSG 570009311 is a solid carbide screw machine length drill bit designed for precision drilling in ferrous and hard materials. It measures 3/32 inch (0.0938 inches) in diameter with a 180-degree drill point angle for flat-bottom and through-hole drilling applications. The web-thinned, tapered web geometry reduces thrust and improves chip evacuation. With two spiral flutes and a right-hand cutting direction, this bit is engineered for high-performance drilling in production and maintenance environments. The straight-cylindrical shank ensures secure chuck engagement. It belongs to OSG Series 5700 and is built for shops and tradespeople who need consistent, repeatable hole quality in demanding materials.

This drill bit is suited for drilling steel, alloy steel, and cast iron in screw machine and short-run production setups. Its compact screw machine length body provides rigidity in CNC machining centers, turret lathes, and drill presses where stub-length reach is preferred over jobber-length flexibility. The 2xD flute-to-diameter ratio keeps the tool stiff in tight-tolerance operations. Machinists, tool-and-die technicians, and maintenance mechanics will find this bit appropriate for tapping prep, pilot holes, and close-tolerance through-holes in hard workpieces.

Key Features

• Solid carbide construction for hardness and wear resistance in ferrous materials
• 180-degree drill point angle for flat-entry and through-hole drilling
• Web-thinned tapered web reduces cutting thrust and improves chip flow
• Right-hand spiral flute, 2xD ratio for rigidity in short-reach applications
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Coated finish for extended tool life in steel and alloy steel

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide drill bit for screw machine length drilling applications in steel, alloy steel, and cast iron workpieces.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with cutting tool handling. Power down and secure the spindle before mounting or removing the bit from the chuck or collet. Verify runout with a dial indicator before production use to protect the tool and workpiece tolerance. Follow machine manufacturer guidelines for feed rate and spindle speed appropriate to solid carbide tooling in the target material.
