Import -22400-E Jobber Drill Bit Letter E 0.25 in Hss

Product Description

The IMPORT -22400-E is a jobber-length twist drill bit sized to Letter E, equivalent to 0.250 inches in diameter. Manufactured from high speed steel (HSS) with an oxide coating, it is designed for general-purpose drilling in metal, wood, and plastics. The 118-degree standard point angle suits a wide range of common materials. With a 4-inch overall length and a 2.75-inch flute length, this bit fits standard 3-jaw chucks and drill presses used daily by machinists, maintenance technicians, and fabricators. The straight-cylindrical shank provides consistent grip and minimal runout in both handheld and stationary drilling equipment.

This drill bit is suited for general-purpose production and maintenance drilling in light industrial, commercial, and trade settings. The right-hand spiral flute evacuates chips efficiently during through-hole and blind-hole operations in mild steel, aluminum, brass, and thermoplastics. Web-thinned construction reduces thrust requirements at entry, making it practical for hand drill and drill press use alike. It is sold individually and carries a minimum order quantity of 12 units, making it appropriate for shop-floor stocking or tool-crib replenishment.

Installation Notes

Installation and use should be performed by machinists, maintenance technicians, or qualified tradespeople familiar with rotating cutting tools. Secure the shank firmly in a properly sized chuck before operating and confirm the workpiece is clamped or fixtured to prevent movement. Always wear appropriate eye protection and follow applicable OSHA and shop-safety guidelines when operating drill equipment. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is damaged.
