Seco 03045992 Screw Machine Drill Bit 9mm Carbide Tialn

Product Description

The SECO 03045992 is a screw machine length drill bit engineered for high-performance drilling in steel and other ferrous workpiece materials. Built from solid carbide, it carries a TiAlN coating that extends tool life under elevated cutting temperatures. The 140-degree split-point geometry with cone relief and web thinning reduces thrust force and self-centers on entry without a pilot hole. At 9.00 mm diameter and 89.00 mm overall length, it fits screw machine and short-reach drilling setups where rigidity and hole quality matter. Coolant-through capability supports high-feed-rate machining in CNC turning centers and machining centers where through-spindle coolant is available.

This drill bit is suited for production machining environments where steel is the primary workpiece material. The 3xD flute-to-diameter ratio and screw machine length make it appropriate for drilling shallow-to-moderate depth holes in a rigid setup. It is used by machinists, tool-and-die technicians, and CNC operators running turning centers, machining centers, or gang-drill setups. The straight cylindrical shank fits standard collet chucks and hydraulic toolholders sized for a 10.00 mm shank diameter. The DIN-standard geometry ensures dimensional predictability across interchangeable tooling systems.

Key Features

• Solid carbide construction for rigidity and wear resistance in steel cutting
• TiAlN coating extends tool life at elevated cutting speeds and temperatures
• 140-degree cone-relief point with web thinning reduces entry thrust and improves self-centering
• Coolant-through design supports high-feed CNC operations with through-spindle coolant
• Straight cylindrical 10.00 mm shank fits standard collet chucks and hydraulic holders
• DIN-standard geometry ensures consistent fitment in interchangeable tooling systems

Compatibility

Designed as an OEM-style replacement fitting the SECO SD203A series. Compatible with collet chucks and hydraulic toolholders accepting a 10.00 mm straight cylindrical shank. Intended for CNC machining centers and turning centers equipped with through-spindle coolant, with steel as the primary workpiece material.

Installation Notes

Installation and tool changes should be performed with the machine in a full stop and lockout-tagout procedures followed per shop safety requirements. Seat the straight shank fully in the toolholder and torque the retention mechanism to the toolholder manufacturer specification before running. Verify runout at the cutting edge with a dial indicator before production cutting. Coolant-through toolholders and spindle connections should be confirmed leak-free before engaging the coolant system at operating pressure.
