Eagle Cutting Tool S400-024-I Hss Stub Drill 3/8 Inch

Product Description

The EAGLE CUTTING TOOL S400-024-I is a 3/8 inch high-speed steel (HSS) stub drill bit with a 135-degree split point tip. Stub drills, also called screw machine length drills, feature a shorter flute and overall length than jobber-length bits, which increases rigidity and reduces deflection during drilling. The 135-degree split point geometry allows the bit to self-center on contact, eliminating the need for a center punch on most materials. This bit is suited for machinists, maintenance technicians, and metalworking professionals working in drill presses, CNC turret lathes, and screw machines.

The S400-024-I is designed for drilling in steel, cast iron, aluminum, copper, brass, and similar metals in production and maintenance environments. Its shorter body length makes it well suited for applications where limited clearance prevents the use of standard jobber-length bits. Typical use cases include machine shops, fabrication facilities, and field maintenance operations requiring accurate, repeatable hole sizing in metal workpieces.

Key Features

• 135-degree split point tip self-centers on contact, reducing walking and eliminating the need for center punching on most materials
• Stub (screw machine) length body provides greater rigidity and reduced deflection compared to jobber-length drill bits
• High-speed steel (HSS) construction offers durability and heat resistance for drilling ferrous and non-ferrous metals
• 3/8 inch diameter for standard hole sizing in metal fabrication and machining applications
• Minimum order quantity of 1 unit allows single-piece procurement

Compatibility

Designed as an OEM-style replacement or direct-use stub drill bit compatible with standard 3/8 inch drill chucks on drill presses, hand drills, and CNC screw machines.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard drill chuck tooling. Secure the bit firmly in the chuck and verify concentricity before operation. Always wear appropriate eye protection and follow applicable machine guarding requirements per OSHA and shop safety standards. Ensure spindle speed is set to a rate appropriate for the workpiece material and bit diameter before drilling.
