Osg 3331070 Screw Machine Drill Bit 0.4213 in Carbide

Product Description

The OSG 3331070 is a solid carbide screw machine length drill bit designed for high-performance drilling in ferrous materials. With a 0.4213-inch (10.70 mm) diameter and a 180-degree flat point angle, this bit delivers clean entry without a pilot hole and is well suited for CNC machining centers and automated production equipment. The two-flute spiral design with a tapered web and web-thinned geometry reduces thrust force and improves chip evacuation. At 90.00 mm overall length and a 10.00 mm straight-cylindrical shank, this is a compact, rigid tool built for screw machine and short-reach applications. Machinists and toolroom technicians working in production environments are the primary users.

This drill bit is intended for use in production drilling of steel, alloy steel, and cast iron. The screw machine length format keeps the tool short and stiff, reducing deflection in tight fixtures or multi-spindle setups. The 2xD flute-to-diameter ratio and regular spiral type make it a straightforward choice for through-hole drilling in moderate-depth applications. The coated finish extends tool life when running at elevated speeds in steel and cast iron. It is a fit for shops running Series 5700 OSG tooling programs or looking for a compatible direct replacement in that class.

Key Features

• Solid carbide construction for rigidity and heat resistance in ferrous materials
• 180-degree flat point angle eliminates the need for a pilot hole or center punch
• Web-thinned, tapered web geometry reduces cutting thrust and entry force
• Two-flute regular spiral design promotes efficient chip evacuation
• Straight-cylindrical 10.00 mm shank fits standard drill chucks and collets
• Coated finish extends cutting edge life in steel and cast iron applications

Compatibility

Designed for drilling steel, alloy steel, and cast iron in screw machine and CNC machining applications. Compatible with standard straight-shank collets and drill chucks accepting a 10.00 mm shank diameter. Part of OSG Series 5700.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians. Secure the shank fully in the collet or drill chuck to the specified grip depth before operation. Power down and de-energize the machine spindle before changing tooling. Do not exceed the recommended surface footage or feed rate for the workpiece material, and verify coolant delivery method is compatible with this tool, as coolant-through is not supported on this bit.
