Seco 02897895 Jobber Drill 6.70mm Solid Carbide 140 Deg

Product Description

The SECO 02897895 is a solid carbide jobber-length drill bit designed for precision hole-making in demanding industrial and metalworking applications. Ground to a 140-degree point angle with an AlCrN (aluminum chromium nitride) coating, this drill delivers high heat resistance and extended tool life when cutting steel, stainless steel, cast iron, and other hard materials. The straight-cylindrical shank measures 8.00 mm in diameter and seats securely in standard drill chucks or collet holders. With two spiral flutes in a regular helix configuration and no coolant-through feature, this bit is suited for conventional drilling setups where external or flood coolant is applied. Part of the SD1105A series, it meets ANSI standards and carries an m7 diameter tolerance for consistent fitment.

This drill is intended for use in CNC machining centers, drill presses, and manual mills across production and job-shop environments. It is rated for ISO material groups P (steel), M (stainless steel), K (cast iron), and H (hard materials), making it a practical choice for fabricators, toolroom machinists, and maintenance technicians who work across multiple metal types. The 7xD flute-to-diameter ratio provides adequate chip clearance for moderate-depth holes without requiring peck cycles on most applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and hard materials
• AlCrN coating improves oxidation resistance and extends tool life at elevated cutting temperatures
• 140-degree split-point angle reduces thrust force and improves self-centering on entry
• Straight-cylindrical shank (8.00 mm diameter) fits standard ER collets and keyed drill chucks
• Two regular spiral flutes with 7xD ratio promote efficient chip evacuation in through-hole and blind-hole drilling
• m7 diameter tolerance ensures consistent hole sizing and repeatable fitment across multiple setups

Compatibility

Designed for use in CNC machining centers, drill presses, and manual mills equipped with standard collet chucks or keyed drill chucks accepting an 8.00 mm straight-cylindrical shank. Rated for ISO material groups P, M, K, and H including steel, stainless steel, cast iron, and hard materials.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool-change position is engaged before inserting or removing the drill. Verify collet or chuck is clean and free of chips before seating the shank, and torque the clamping nut to the toolholder manufacturer's specification. Apply appropriate cutting fluid or flood coolant at the entry point to maintain tool life, as this drill does not feature internal coolant-through passages.
