Jobber Drills

Jobber drills deliver clean, accurate holes that set your projects up for success right from the first pass. Our jobber drills balance reach and rigidity so you can drill confidently in handheld tools or on a press without the wobble that ruins tolerances. Choose the sizes you need and count on consistent performance from pilot hole to final fit.

Jobber Drills Overview

Our jobber drills are general-purpose bits with standardized flute lengths and common point angles, built to make straight, true holes with minimal fuss. They’re ideal for pre-drilling before tapping or for creating clearance holes so fasteners seat perfectly, and they’re available in tightly stepped sizes so you can dial in the exact fit your hardware requires. Use them across everyday fabrication, maintenance, assembly, or install work where reliability and repeatability matter.

A good drill shouldn’t distract you. Our geometry guides the cut and helps the bit center quickly, so you can drop into the hole path with less walking and fewer re-starts. The consistent flute length clears chips efficiently to reduce heat buildup, protect the cutting edge, and keep hole walls smooth for better thread engagement later.

For a complete fastening solution, pair your selected jobber drill with our Powercoil Insert Kits when you need strong threads in softer parent material, or finish assemblies with our Fully Threaded Stud and Double Ended Stud options for secure, predictable clamping.

Built for Smooth, True Holes

Chip control is everything, and our flute design keeps material moving out of the way so the cutting edge can do its job. That means cooler cutting, less friction, and a cleaner sidewall that sets you up for confident tapping and precise fastener fit. The result is a hole that measures up visually and functionally, with fewer surprises once you move to the next operation.

Ready for Your Setup

Whether you are running a drill press, a mill, or a handheld driver, these bits integrate seamlessly into your process. The shank profile seats securely, starts feel controlled, and feeds remain consistent so you can hold your line and finish on schedule. Keep them in your index and you will have an answer for everything from fixture plates to brackets to field installs.

Everyday Reliability, Shop-Proven

You do not have time for trial and error. Our jobber drills are made for repeatable outcomes that reduce rework, protect your parts, and keep your team moving. Count on them for clean entries, minimal chatter, and a surface that sets the stage for fasteners to seat right the first time.

FAQs

What is a jobber drill used for?

A jobber drill is a general-purpose drill bit used to produce pilot and clearance holes for fasteners, as well as holes for pins, rivets, and general fabrication. Its standardized flute length and point geometry make it versatile for handheld drills and drill presses. In short, it’s the everyday bit you rely on for accurate, repeatable holes.

What materials can jobber drills drill into?

Jobber drills are commonly used on wood, plastics, and non-ferrous metals such as aluminum and brass, and they also handle mild and low-alloy steels with proper speed and feed. Always match your drilling parameters to the workpiece and keep chips clear to control heat and preserve accuracy. For especially hard or abrasive materials, use appropriate techniques and consult recommended cutting data.

Why are jobber drills the most common drill bits?

They offer the best balance of reach, chip evacuation, and stiffness for everyday work. Because the length and geometry are standardized, you get predictable performance across a huge size range. That combination of versatility and consistency is why most toolboxes start with jobber drills.

How do I choose the right size jobber drill?

Match the drill size to your application: use tapping charts for pilot holes and hardware specs for clearance holes. Metric, fractional, and letter/number sizes let you fine-tune the fit, so choose the size that delivers the thread engagement or clearance your design calls for. When tolerances are tight, step through pilots and measure as you go to confirm the perfect result.
