Seco 03046194 Jobber Drill 7.50 Mm Solid Carbide Tialn

Product Description

The SECO 03046194 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous and hard materials. Built on the SD205A series platform, it features a 7.50 mm cutting diameter, a 140-degree split point for accurate self-centering entry, and a TiAlN coating that extends tool life under elevated cutting temperatures. The straight-cylindrical shank measures 8.00 mm in diameter, compatible with standard drill chucks and collet holders. With a right-hand spiral flute and a flute-to-diameter ratio of 7xD, this drill is suited for demanding production environments where chip evacuation and hole quality are both critical.

This drill is intended for use in steel, stainless steel, cast iron, and other hard materials classified under ISO material groups P, M, K, and H. It is appropriate for CNC machining centers, drill presses, and manual machines where a standard ANSI-spec jobber drill is required. The 53.00 mm flute length supports drilling depths up to 43.00 mm, making it well-suited for through-hole and blind-hole applications in medium to heavy-duty production and job shop settings. Licensed machinists and toolroom technicians are the primary users of this tool.

Key Features

• Solid carbide construction for rigidity and heat resistance in hard-material drilling
• TiAlN coating improves wear resistance and thermal stability at the cutting edge
• 140-degree point angle promotes accurate entry and reduces walking on flat surfaces
• Right-hand spiral flute with regular spiral type ensures efficient chip evacuation
• Straight-cylindrical shank fits standard chucks and collet holders without adapters
• ANSI-compliant dimensions for drop-in compatibility with existing tooling setups

Compatibility

Designed as an OEM-style replacement or direct-application drill bit for use in CNC machining centers and conventional drill presses accepting an 8.00 mm straight-cylindrical shank. Compatible with ISO material groups P, M, K, and H as specified by the manufacturer.

Installation Notes

Installation and use of this tool should be performed by a qualified machinist or toolroom technician. Before mounting, ensure the spindle and chuck or collet holder are clean, properly sized for an 8.00 mm shank, and securely tightened to prevent runout. Power down and lock out the machine before inserting or removing the drill bit. Do not exceed the manufacturer-rated maximum drilling depth of 43.00 mm, and verify workpiece fixturing is secure before starting the cut.
