Eagle Cutting Tool S304-116-I Cobalt Jobber Drill Bit

Product Description

The EAGLE CUTTING TOOL S304-116-I is a Number 16 cobalt jobber-length drill bit designed for drilling into hard metals, stainless steel, cast iron, and other tough materials that standard high-speed steel bits struggle with. Cobalt construction provides superior heat resistance, making it well suited for demanding production and maintenance drilling applications. At 0.4 pounds, the bit is lightweight and easy to handle. It is commonly used by machinists, pipefitters, electricians, and HVAC technicians who need reliable performance when drilling through hard ferrous and non-ferrous metals on the job.

This jobber drill bit is appropriate for both shop and field use wherever a Number 16 diameter hole is required. Typical applications include drilling pilot holes for tapping threads, creating clearance holes in sheet metal and structural steel, and general-purpose metal fabrication tasks. The jobber-length flute design provides a good balance of reach and rigidity for most standard drilling scenarios. Professionals across mechanical, electrical, and plumbing trades keep cobalt jobber bits on hand for work on equipment housings, mounting brackets, and metal enclosures.

Key Features

• Cobalt construction for extended heat resistance during high-speed drilling into hard metals
• Number 16 wire gauge sizing for precise hole diameter control
• Jobber-length flute provides versatile reach suitable for most standard drilling tasks
• Lightweight at 0.4 pounds for easy single-hand use and transport
• Minimum order quantity of 1 allows single-unit purchase for maintenance and service needs

Compatibility

Designed as a standard Number 16 jobber-length drill bit compatible with conventional keyed and keyless drill chucks that accept round-shank bits.

Installation Notes

A licensed machinist or qualified tradesperson should secure the bit firmly in a properly rated drill chuck before use. Always use appropriate cutting fluid or lubricant when drilling hard metals to extend bit life and reduce heat buildup. Eye protection and appropriate PPE are required when operating rotary cutting tools. Inspect the cutting edges for wear or chipping before each use and replace the bit if damage is detected.
