Seco 03046350 Solid Carbide Jobber Drill 17/32 Inch

Product Description

The SECO 03046350 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding metalworking applications. It carries a TiAlN coating and a 140-degree point angle suited for hard and abrasive materials. The bit measures 17/32 inch (0.5313 inch) in diameter with an overall length of 4.8819 inches and a flute length of 3.0315 inches. A straight-cylindrical shank with a 0.5512-inch shank diameter ensures secure chuck engagement. This drill belongs to the SD205A series and is built for right-hand, spiral-flute cutting. It is installed and used by machinists, tool-and-die professionals, and maintenance technicians working with steel, stainless steel, cast iron, and other hard materials.

The 03046350 is intended for production and maintenance drilling in ferrous and hard material applications. Its 5xD flute-to-diameter ratio supports chip evacuation in deeper holes up to a maximum drilling depth of 3.0315 inches. The 140-degree point geometry reduces thrust and walking on entry, making it well suited for drilling steel, stainless steel, cast iron, and hard materials (material codes P, M, K, H). This bit does not feature coolant-through capability and is designed for use in standard drill presses, machining centers, and CNC setups where a straight-cylindrical shank is appropriate.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• TiAlN coating improves heat resistance and extends tool life in ferrous cutting
• 140-degree point angle reduces entry thrust and minimizes workpiece damage
• Right-hand spiral flute with regular helix promotes consistent chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• ANSI-standard tolerances (m7 diameter tolerance) for precise fit and repeatability

Compatibility

Designed for use in steel, stainless steel, cast iron, and hard materials (ISO material codes P, M, K, H). Fits standard drill chucks and collet systems accepting a 0.5512-inch straight-cylindrical shank. Part of the SECO SD205A series.

Installation Notes

This drill bit is installed by machinists and maintenance technicians in drill presses, machining centers, or CNC equipment. Secure the straight-cylindrical shank fully in the chuck or collet before operation and verify runout before cutting. Always power down and lock out the machine before changing tooling. Follow machine manufacturer feed and speed recommendations for the specific workpiece material to avoid premature edge wear or bit failure.
