Seco 03046346 Jobber Drill Bit 27/64 Inch Solid Carbide

Product Description

The SECO 03046346 is a solid carbide jobber length drill bit engineered for demanding metal cutting applications. It carries a 27/64 inch (0.4219 inches) diameter with a 140-degree point angle and a TiAlN coating that extends tool life under high-temperature cutting conditions. The straight-cylindrical shank measures 0.4724 inches in diameter and 1.7717 inches in length, fitting standard drill chucks without adapters. With an overall length of 4.6457 inches and a two-flute spiral design, this bit delivers efficient chip evacuation during deep-hole drilling. It belongs to SECO Series SD205A and is built to ANSI standards. Licensed machinists, tool-and-die tradespeople, and maintenance mechanics are the primary users of this bit.

This drill bit is designed for right-hand cutting in steel, stainless steel, cast iron, and other hard materials designated under ISO material groups P, M, K, and H. The 6xD flute-to-diameter ratio supports drilling depths up to 2.7953 inches, making it suitable for production drilling in fabrication shops, aerospace maintenance environments, and industrial maintenance operations. No coolant-through capability is built in, so external coolant or cutting fluid application is standard practice for this configuration.

Key Features

• Solid carbide construction provides rigidity and wear resistance in hard and abrasive workpiece materials
• TiAlN coating improves heat resistance and extends cutting edge life in dry or minimal-lubrication setups
• 140-degree point angle reduces thrust force and walking on entry, particularly useful on hard metals
• Two-flute regular spiral geometry promotes consistent chip evacuation in deep-hole applications
• Straight-cylindrical shank (0.4724 inches diameter) fits standard drill chucks without special toolholders
• Maximum drilling depth of 2.7953 inches within a compact 4.6457-inch overall length

Compatibility

Designed for use in CNC machining centers, drill presses, and handheld power tools equipped with standard straight-shank chucks accepting a 0.4724-inch shank diameter. Primary workpiece materials include steel, stainless steel, cast iron, and other hard materials per ISO designations P, M, K, and H.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with cutting tool safety. Secure the shank fully in the chuck or collet and verify runout before cutting. Power down and de-energize all equipment before changing or inspecting the bit. Since this bit does not include coolant-through channels, apply external cutting fluid or coolant at the cutting zone to manage heat buildup during prolonged drilling cycles.
