Sgs 51025 Jobber Drill Bit Wire 25 Solid Carbide 118

Product Description

The SGS 51025 is a jobber-length drill bit engineered for precision drilling in metal, composites, and other hard materials. Manufactured from micrograin solid carbide, this bit delivers superior hardness and wear resistance compared to high-speed steel alternatives. It carries a wire gauge size of 25, equating to 0.1495 inches (3.80 mm) in diameter, and features a 118-degree faceted point angle with web thinning for easier penetration and reduced thrust force. The bright, uncoated finish is suitable for general-purpose machining where coating is not required. Machinists and tooling professionals install this bit in CNC machining centers, drill presses, and manual drilling setups.

This bit is designed for jobber-length applications where a standard reach-to-diameter ratio is required. The 5xD flute-to-diameter ratio and 1.375-inch flute length accommodate moderate-depth drilling. With a straight cylindrical shank measuring 0.1495 inches in diameter and a shank length of 1.125 inches, the 51025 seats securely in standard drill chucks and collet systems. It is suited for shops performing production drilling, toolroom work, or precision part fabrication where tight diameter tolerances are critical.

Key Features

• Micrograin solid carbide construction for high hardness and extended tool life
• 118-degree faceted point with web thinning reduces entry thrust and improves centering
• Right-hand spiral flute promotes efficient chip evacuation
• Bright uncoated finish suitable for dry cutting or use with standard cutting fluids
• Straight cylindrical shank for broad chuck and collet compatibility
• Conforms to DIN 338 standard for jobber-length drill geometry

Compatibility

Designed as a jobber-length drill bit for use in standard drill chucks and collet holders accepting a 0.1495-inch straight cylindrical shank, compatible with CNC machining centers, drill presses, and hand drilling equipment configured for wire-gauge tooling.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the shank fully within the chuck or collet and verify runout before initiating a cut. Do not exceed the rated maximum drilling depth of 1.109 inches per pass without retracting to clear chips. Carbide tooling is brittle and susceptible to chipping under lateral load or impact - avoid side loading and handle with care during storage and setup.
