Seco 03046348 Jobber Drill Bit 29/64 in Solid Carbide Tialn

Product Description

The SECO 03046348 is a jobber length drill bit designed for high-performance drilling in demanding industrial and trade environments. Built from solid carbide with a TiAlN coating, this bit delivers extended tool life and thermal resistance in applications where standard high-speed steel tooling falls short. The 140-degree point angle reduces thrust force and improves chip evacuation at entry. With a diameter of 29/64 inch (0.4531 inch) and an overall length of 4.6457 inches, it suits a wide range of CNC and manual drilling operations. It is part of the SD205A series and follows ANSI standards. Machinists, tool and die makers, and precision drilling operators are the primary users of this bit.

The 03046348 is engineered for drilling steel, cast iron, and hardened materials, covering ISO workpiece material codes P, M, K, and H. Its regular spiral flute geometry and right-hand cut make it compatible with standard drill presses, machining centers, and CNC setups. The 6xD flute-to-diameter ratio supports drilling to a maximum depth of 2.7953 inches (71.00 mm). The straight cylindrical shank with a 0.4724 inch diameter fits standard toolholders without modification. This bit does not require coolant-through capability, simplifying setup in shops without through-spindle coolant systems.

Key Features

• Solid carbide construction with TiAlN coating for extended wear resistance and heat tolerance
• 140-degree point angle reduces entry thrust and improves centering accuracy
• Right-hand cut with regular spiral flutes for reliable chip clearance in ferrous materials
• 6xD flute ratio supports drilling depths up to 2.7953 inches without pausing for chip clearing
• Straight cylindrical shank at 0.4724 inch diameter fits standard drill chucks and collet holders
• ANSI-compliant SD205A series bit rated as high-performance grade for production environments

Compatibility

Designed for drilling steel, cast iron, and hardened materials (ISO material codes P, M, K, H) in standard drill presses, machining centers, and CNC equipment accepting a 0.4724 inch straight cylindrical shank.

Installation Notes

Installation and operation should be performed by qualified machinists or tooling technicians familiar with rotating cutting tool safety. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the toolholder. Confirm the shank is fully seated and the chuck or collet is properly torqued before initiating a cut. Follow the machine manufacturer and applicable ANSI safety guidelines for speeds and feeds appropriate to the workpiece material.
