Seco 03046010 Drill Bit 11mm Solid Carbide Tialn SD203A

Product Description

The SECO 03046010 is a screw machine length drill bit designed for high-performance metal cutting in demanding shop and production environments. Built from solid carbide with a TiAlN coating, it delivers superior wear resistance and heat tolerance compared to high-speed steel tooling. The 140-degree cone relief point geometry promotes accurate entry and reduced thrust force. At 11.00 mm in diameter with an overall length of 102.00 mm (approximately 4.02 inches), this bit fits standard straight-shank tool holders and is suited for CNC machining centers, drill presses, and automated production cells. It is typically installed and operated by machinists and tooling professionals.

This drill bit is intended for right-hand cutting in steel and similar primary workpiece materials. The screw machine length format provides added rigidity over jobber-length bits, making it appropriate for close-tolerance through-hole and blind-hole drilling where runout and deflection must be minimized. The SD203A series targets high-volume production applications where consistent hole quality and tool life are priorities. Coolant-through capability supports chip evacuation and thermal management during extended cutting cycles at aggressive feed and speed parameters.

Key Features

• Solid carbide construction with TiAlN proprietary coating for extended tool life in steel applications
• 140-degree cone relief point for accurate self-centering and reduced thrust on entry
• Coolant-through design aids chip evacuation and controls cutting-zone temperature
• Web-thinned geometry lowers cutting resistance and improves penetration efficiency
• Straight-cylindrical shank (12.00 mm diameter) fits standard collets and drill chucks without modification
• Regular spiral flute with 3xD flute-to-diameter ratio balances chip flow and rigidity

Compatibility

Designed as an OEM-style production drill bit in the SECO SD203A series, compatible with straight-shank tool holders and collet chucks accepting a 12.00 mm shank diameter. Drill bit diameter tolerance is m7 per DIN standards.

Installation Notes

Installation and operation should be performed by qualified machinists or tooling technicians familiar with CNC or manual drilling equipment. Ensure the machine spindle and tool holder are clean and free of chips before seating the shank. Confirm coolant-through passages are clear and coolant pressure is set per machine specifications before initiating a cut. Do not exceed the maximum drilling depth of 40.00 mm per pass without retracting to clear chips.
