Osg 62620 Jobber Length Drill Bit 12 Mm Tin Coated

Product Description

The OSG 62620 is a jobber-length twist drill bit designed for precision hole-making in ferrous and non-ferrous metals. Built from vanadium high speed steel with a titanium nitride (TiN) coating, this bit delivers extended tool life and reduced friction in demanding production and maintenance environments. It measures 12 mm in diameter with an overall length of 158 mm and a flute length of 101 mm. The 120-degree S-thinned point promotes self-centering entry and reduces thrust force, making it well suited for general-purpose drilling in steel, stainless steel, aluminum, and aluminum alloys. Machinists, toolroom technicians, and maintenance tradespeople are the primary users.

This bit is rated for blind hole drilling, cross-hole drilling, through-hole drilling, and self-centering applications across a wide range of base materials including steel, stainless steel, aluminum, and aluminum silicate. The straight-cylindrical shank accommodates standard drill chucks on machine tools, drill presses, CNC machining centers, and handheld power drills. It fits within the 10 mm to 12.5 mm drill bit size range class and carries an UNSPSC commodity code of 23241634, which can assist with procurement classification in MRO and industrial supply systems.

Key Features

• Vanadium high speed steel construction for toughness and wear resistance in metal cutting
• Titanium nitride (TiN) coating reduces friction, improves surface hardness, and extends service life
• 120-degree drill point angle with S-thinned web for self-centering entry and lower thrust requirements
• Regular spiral flute geometry promotes consistent chip evacuation in through and blind hole applications
• Straight-cylindrical shank compatible with standard drill chucks across machine tool and handheld platforms
• Tapered web configuration adds rigidity and supports performance in cross-hole and interrupted-cut scenarios

Compatibility

Designed as an OEM-style jobber-length drill bit suitable for use in standard drill chucks accepting a 12 mm straight-cylindrical shank, compatible with steel, stainless steel, aluminum, and aluminum alloy workpieces as noted in the product specifications.

Installation Notes

Installation and use should be performed by machinists, toolroom technicians, or qualified maintenance tradespeople familiar with metal cutting operations. Secure the shank fully in the drill chuck and verify runout before beginning a cut. Follow the machine manufacturer's recommended speeds and feeds for the workpiece material and drill diameter. Wear appropriate eye protection and secure workpieces firmly to prevent movement during drilling.
