Eagle Cutting Tool S400-027-I Hss Stub Drill 27/64

Product Description

The EAGLE CUTTING TOOL S400-027-I is a 27/64-inch high-speed steel (HSS) stub-length drill bit designed for metal drilling applications in production and maintenance environments. The stub-length body provides increased rigidity compared to jobber-length drills, reducing deflection and chatter when drilling in tight spaces or through harder materials. At 0.95 pounds, it is a compact, durable tool suited for use in hand drills, drill presses, and CNC setups. Machinists, pipefitters, electricians, and general trade professionals rely on stub drills where a shorter flute length improves hole accuracy and bit longevity.

This drill bit is appropriate for use in light manufacturing, mechanical rooms, and field service work where 27/64-inch clearance or pilot holes are required. Common applications include drilling through mild steel, aluminum, and similar ferrous and non-ferrous materials. The stub geometry is particularly useful when drilling through structural members, panel enclosures, or equipment frames where reach is limited and a standard-length bit would flex or wander.

Key Features

• 27/64-inch diameter HSS construction for durability across a range of metals
• Stub-length design increases rigidity and reduces deflection in confined spaces
• Compatible with standard drill chucks on hand drills, drill presses, and CNC machines
• Lightweight at 0.95 pounds for easy handling during overhead or positional drilling
• Minimum order quantity of 1 for flexible purchasing

Compatibility

Designed as a standard-shank stub-length drill bit compatible with any drill press, hand drill, or CNC spindle accepting a 27/64-inch HSS bit with a straight shank.

Installation Notes

Installation is performed by machinists, maintenance technicians, and trade professionals using standard drill chucks. Secure the bit fully in the chuck before operation and confirm the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid or lubricant when drilling ferrous materials to extend bit life and improve hole finish. Inspect the cutting edges for wear or chipping before each use and replace if the bit shows signs of dulling.
