Seco 03046030 Screw Machine Drill Bit 13mm Carbide Tialn

Product Description

The SECO 03046030 is a solid carbide screw machine length drill bit designed for high-performance drilling in steel and other ferrous workpiece materials. It features a 13.00 mm diameter with a 140-degree cone relief point angle, a TiAlN coating for heat and wear resistance, and coolant-through capability to support aggressive feed rates and extended tool life. The overall length is 107.00 mm with a flute length of 60.00 mm and a maximum drilling depth of 43.00 mm. This bit belongs to the SD203A series and is built to DIN standards. It is installed and used by machinists and tool-and-die professionals in production drilling environments.

This drill bit is suited for screw machine and short-hole drilling operations on steel workpieces where precision and repeatability are required. The web-thinned geometry reduces thrust forces and improves chip evacuation. Coolant-through design supports high-speed production drilling setups where external coolant alone is insufficient. The straight cylindrical shank with a 14.00 mm shank diameter seats directly into collets, drill chucks, or hydraulic toolholders sized for that diameter. Typical applications include CNC machining centers, drill presses, and screw machines running at production volumes.

Key Features

• Solid carbide construction for rigidity and wear resistance in steel cutting
• TiAlN coating extends tool life under high heat and dry or near-dry cutting conditions
• 140-degree cone relief point reduces thrust and centers quickly on the workpiece
• Coolant-through design delivers cutting fluid directly to the cutting edge for deep-hole operations
• Web-thinned geometry reduces cutting forces and improves chip flow
• DIN-standard construction with m7 diameter tolerance for consistent fit in precision toolholders

Compatibility

Part of the SECO SD203A series, designed for use in straight-shank toolholders, collets, and chucks accepting a 14.00 mm shank diameter. Drill bit size range covered by this series is 11.00 mm to 13.50 mm. Primary workpiece material is steel.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with carbide tooling. Ensure the machine spindle and toolholder are powered down and at a full stop before inserting or removing the bit. Verify the toolholder bore matches the 14.00 mm shank diameter to prevent runout. Avoid impact-style tightening methods that can chip carbide shanks; use torque-controlled toolholder clamping per the toolholder manufacturer instructions.
