Osg 8672430 Solid Carbide Jobber Drill 4.30 Mm 140 Deg

Product Description

The OSG 8672430 is a solid carbide jobber-length drill bit designed for high-performance drilling in steel, alloy steel, and cast iron. It features a 4.30 mm diameter with a 140-degree point angle and an R-thinned web geometry that promotes self-centering and reduces thrust on entry. The EgiAs coating improves wear resistance and tool life in demanding ferrous materials. With an overall length of 74.00 mm and a 36.00 mm flute length, this drill handles blind hole, cross hole, and through-hole drilling in production and maintenance environments. It is sized in the 5xD flute-to-diameter ratio range and carries a straight-cylindrical shank at 6.00 mm diameter.

This drill bit is suited for use in CNC machining centers, drill presses, and handheld power tools where precise hole diameter control in ferrous materials is required. The 2-flute, right-hand spiral configuration provides efficient chip evacuation in steel and cast iron applications. It falls within the OSG Series 6310 product line, which targets high-performance jobber drilling in the 4.00 mm to 5.00 mm diameter range. Typical users include machinists, tool-and-die technicians, and maintenance professionals working in industrial and commercial fabrication settings.

Key Features

• EgiAs coating extends tool life and reduces friction in steel and alloy steel
• 140-degree point angle with R-thinned web for self-centering entry and reduced thrust
• 2-flute right-hand spiral design promotes efficient chip evacuation
• Straight-cylindrical 6.00 mm shank fits standard drill chucks and collet systems
• Diameter tolerance held to +0 to -0.018 mm for consistent hole quality

Compatibility

Designed for drilling steel, alloy steel, and cast iron workpieces. Suited for blind hole, cross hole, general drilling, and self-centering applications within the 4.00 mm to 5.00 mm diameter range, per OSG Series 6310 tooling specifications.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with cutting tool safety procedures. Before installing or removing this drill bit, ensure the spindle is fully stopped and the machine is de-energized or locked out per applicable safety protocols. Verify that the chuck or collet is rated for the 6.00 mm shank diameter and is tightened to the equipment manufacturer's specification. Coolant-through is not supported on this tool; external coolant or dry cutting conditions should be selected based on material and feed-rate requirements.
