Seco 02897881 Solid Carbide Drill Bit 7/32 in 140 Deg

Product Description

The SECO 02897881 is a solid carbide jobber length drill bit designed for high-performance drilling in demanding materials. Sized at 7/32 inch (0.2187 inch decimal), it features a 140-degree drill point angle for accurate self-centering entry and reduced thrust. The AlCrN coating provides heat and wear resistance during extended cutting cycles. With an overall length of 3.2283 inches (82 mm) and a 2-flute regular spiral design, this bit delivers efficient chip evacuation and stable cutting geometry. It is suited for machinists, tool and die technicians, and metalworking professionals who require consistent hole quality in tough workpiece materials.

The 02897881 is engineered for drilling steel, stainless steel, cast iron, and other hard materials. Its Series SD1105A classification places it in SECO's high-performance drilling line, with a 7xD flute-to-diameter ratio that supports drilling depths up to 1.7323 inches (44 mm). The straight-cylindrical shank at 0.2362 inch (6 mm) diameter seats securely in standard drill chucks and collet holders. No coolant-through capability is present, making it appropriate for dry or externally cooled drilling setups on CNC machining centers and manual drill presses alike.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlCrN coating improves heat resistance and extends tool life in steel and stainless steel applications
• 140-degree standard point angle reduces walking and entry burr formation
• 2-flute regular spiral design promotes efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks and collet toolholding systems
• Conforms to ANSI standards for consistent dimensional accuracy

Compatibility

Designed for use in drilling applications involving steel (P), stainless steel (M), cast iron (K), and hard materials (H) per ISO workpiece material codes. Compatible with standard drill chucks and collet holders accepting a 0.2362 inch (6 mm) straight-cylindrical shank. Suitable for CNC machining centers and manual drill presses where external coolant or dry cutting is employed.

Installation Notes

Installation and use should be performed by qualified machinists or metalworking technicians familiar with cutting tool safety practices. Ensure the machine spindle is fully stopped and the tool holder is properly torqued before beginning any drilling operation. Verify shank seating depth and runout in the collet or chuck before cutting. Do not use this bit in applications requiring coolant-through delivery, as the tool does not support internal coolant channels.
