Alpha 1/8" Jobber Drill Bit — High-Speed Steel All-Purpose Precision Tool

The Alpha 1/8" Jobber Drill Bit is a compact, reliable precision tool designed to tackle everyday drilling across metal, wood, and plastic. Built with a classic jobber geometry and a standard-length shank, this bit delivers steady rigidity and contro l for clean pilot holes and small-diameter work in any workshop, lab, or home project space.

Why this 1/8" jobber bit stands out

• Versatile entry geometry: 118° general-purpose point for smooth starts in a variety of materials, with a 135° option available for harder metals for improved control and reduced walking.
• Durable material: High-Speed Steel (HSS) core enhances heat resistance and wear life, helping you maintain sharpness through repeated use.
• Coatings to match the job: Choose from Titanium, Cobalt, or Black Oxide coatings to tailor friction, heat tolerance, and longevity to your material suit—whether it’s steel, aluminum, or plastics.
• Broad compatibility: Straight shank fits most drill chucks, hand drills, drill presses, and CNC machines, making it a reliable staple in metalworking, woodworking, electronics enclosures, cabinetry, and general construction.
• Consistent, repeatable results: The combination of robust HSS construction, proven point geometry, and option coatings minimizes wander and tear-out, delivering accurate starts and clean holes from the first to the last job.

What it can do for you

Whether you’re drilling quick pilot holes for fasteners, creating precise entry points in sheet metal, or making delicate cuts in plastics and composites, this 1/8" jobber drill bit keeps your projects on track. It’s ideal for DIYers tackling cabinetry, electronics enclosures, hobby metalworking, and small-scale wood projects where repeatable accuracy matters. The bit’s size makes it a natural choice for anchors, pilot holes, and starting points that set the stage for reliable, snug-fit hardware and clean, finished work.

Durability meets practicality

Using the right coating and geometry extends tool life without complicating your workflow. Titanium coatings reduce friction and heat buildup, cobalt coatings resist wear in tougher metals, and black oxide provides a cost-effective resilience for mixed-material tasks. The 1/8" diameter, combined with Alpha’s HSS core, balances speed and control—so you can drill with confidence in metal, wood, and plastic alike.

Tips for best results

• Match the point angle to the material: 118° for general use; opt for the 135° variant when drilling harder metals to minimize wandering.
• Secure workpieces and use steady feeds to maximize hole quality and tooling life.
• When drilling plastics or composites, consider a lighter feed to prevent chip buildup and heat.
• Pair the bit with compatible coatings suited to the material you’re working with to extend service life and maintain sharpness.
