Seco 02897906 Solid Carbide Jobber Drill 19/64 in 140 Deg

Product Description

The SECO 02897906 is a solid carbide jobber-length drill bit in the SD1105A series, designed for high-performance drilling in demanding materials. It carries a 19/64 inch (0.2969 inch) diameter with a 140-degree standard point angle and an AlCrN (aluminum chromium nitride) coating for extended tool life. The straight-cylindrical shank measures 0.3150 inch in diameter. Overall length is 3.5827 inches (91.00 mm), with a flute length of 2.0866 inches (53.00 mm). Right-hand cutting with regular spiral flutes and a 7xD flute-to-diameter ratio, this bit is suited for precision drilling where consistent hole quality and tool durability are priorities. Machinists and tool-and-die professionals are the typical end users.

The 02897906 is intended for drilling steel, stainless steel, cast iron, and other hard materials, corresponding to ISO material codes P, M, K, and H. It is well suited for CNC machining centers and manual mills where a straight-cylindrical shank can be secured in standard collets or drill chucks. The 7xD depth-to-diameter ratio supports moderate-depth holes without requiring pecking cycles in many applications. No coolant-through capability is present, so external or flood coolant delivery should be used when drilling harder alloys or deep holes.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlCrN coating reduces heat buildup and extends tool life in steel and stainless steel
• 140-degree point angle reduces thrust and improves centering on entry
• Regular spiral, 2-flute design for efficient chip evacuation
• Straight-cylindrical shank (0.3150 inch / 8.00 mm diameter) fits standard collets and chucks
• ANSI standard compliance; diameter tolerance m7

Compatibility

Designed as an OEM-style tooling option for CNC machining centers, drill presses, and manual milling machines accepting a straight-cylindrical shank. Rated for primary workpiece materials including steel, stainless steel, cast iron, and hard materials (ISO codes P, M, K, H).

Installation Notes

Installation is performed by machinists or CNC operators. Secure the straight-cylindrical shank in a properly sized collet or drill chuck, ensuring full shank engagement to the recommended depth before tightening. Confirm spindle speed and feed rate are appropriate for the workpiece material and drill diameter before starting the cut. Because this bit has no coolant-through capability, apply adequate external or flood coolant to manage heat, particularly when drilling stainless steel or other hard alloys.
