Value Collection 01358548 Size 54 Screw Machine Drill Bit

Product Description

The VALUE COLLECTION 01358548 is a screw machine length drill bit engineered for general-purpose drilling in metal, wood, and plastics. The stub-length design provides added rigidity compared to jobber-length bits, reducing deflection in short-reach and machine-tool applications. Ground from high-speed steel (HSS) with an oxide finish for basic lubricity and surface protection, this bit features a 118-degree standard point angle suitable for most common materials. The straight cylindrical shank seats securely in standard drill chucks and quick-change holders. Overall length is 1-5/8 inches with a 5/8-inch flute length.

This bit is sized to wire gauge No. 54, equivalent to 0.0550 inches in decimal inch. That small diameter is commonly used in tapping pilot holes, through-hole work on printed circuit assemblies, precision sheet metal, and instrumentation component drilling. The screw machine length format makes it especially practical in drill presses, CNC machining centers, and benchtop applications where minimal bit overhang is required for accuracy. Right-hand spiral flutes evacuate chips cleanly during the cut.

Key Features

• Wire gauge No. 54 size — 0.0550-inch decimal equivalent for precision small-diameter drilling
• HSS construction with oxide coating for general-purpose durability and basic lubrication
• 118-degree standard point angle compatible with a wide range of workpiece materials
• Screw machine (stub) length reduces deflection and improves hole accuracy in tight setups
• Right-hand cut with 2 regular spiral flutes for efficient chip evacuation
• Straight cylindrical shank fits standard drill chucks and quick-change toolholders

Compatibility

Designed as a general-purpose screw machine length drill bit suitable for use in drill presses, CNC machining centers, and hand-held drill tools accepting a straight cylindrical shank in the 0.0550-inch diameter range.

Installation Notes

A licensed machinist or experienced technician should secure the shank fully in the chuck before operation and confirm runout is within acceptable limits for small-diameter tooling. Power down and lock out the machine before changing or inspecting the bit. At this diameter, excessive feed pressure or misalignment is the primary cause of breakage — use consistent, light feed pressure and appropriate cutting fluid for the workpiece material.
