Key Features
Overview
The Kreg Easy-Set Drill Bit with Stop Collar & Gauge/Hex Wrench, Model KPHA308, is a replacement and add-on accessory set for Kreg pocket-hole jigs. This is a pocket-hole drill bit accessory kit designed for drilling pocket holes in common woodworking material thicknesses. If you want a second setup ready to go, or you are replacing worn parts from your jig, this kit gives you the stepped drill bit, matching stop collar, and thickness gauge/hex wrench in one package.
What matters here is setup speed. The stepped drill bit has easy-set etched markings for 1/2 inch, 3/4 inch, and 1-1/2 inch material, and the stop collar window is made to align with those markings. That means less fiddling with measurements and fewer chances to set the bit wrong. On pocket-hole jigs, bad setup shows up fast as weak joints, blowout, or screw tips poking through. This setup is meant to keep that from happening.
The bit works with material from 1/2 inch to 1-1/2 inch thick, which covers a lot of real shop and jobsite work: cabinet parts, plywood cases, face frames, utility shelving, and basic furniture builds. The included thickness gauge helps you verify stock thickness before you drill, and it has a built-in hex wrench for adjusting the collar. That is the kind of small detail that saves time because the setup tool is already in your hand instead of buried in a drawer.
Kreg designed this as the same stepped bit system included with several of its newer pocket-hole jigs, so it is a direct replacement when your original bit is worn or when you want a second complete drilling setup. For anyone running repeated pocket-hole joinery, having a spare bit and collar ready is not a luxury. It keeps the work moving when one setup is dedicated to one material thickness and another is set for something else.
The 1/4 inch hex shank fits standard quick-change chucks, which makes this easy to use with common drills and drivers that accept hex accessories. That is useful in small shops and on mobile jobs where you are not running a dedicated drill press or specialty machine. Swap it in, set the collar, confirm material thickness, and get to work.
Compatibility is broad across the Kreg lineup. It is made for Kreg Pocket-Hole Jigs, excluding Micro and XL models, and it is listed as a direct replacement for the parts included with the Pocket-Hole Jig 320, 310, 520PRO, 720, and 720PRO. It also works with K5, K4, K3, R3, Mini, and Foreman DB210. If you are already in the Kreg pocket-hole system, that wide fit is a big reason this accessory matters.
This kit makes the most sense for woodworkers, cabinet installers, trim carpenters, and serious DIY builders who use pocket-hole joinery often enough to appreciate a faster setup and a ready spare. If you only drill a few holes a year, your original parts may be enough. If you build regularly, having the Kreg Easy-Set Drill Bit with Stop Collar & Gauge/Hex Wrench on hand is just smart shop insurance.
Dial In the Right Depth Fast
The whole point of this setup is getting from material check to drilling without stopping to second-guess collar position.
- Etched markings on the stepped drill bit match common stock sizes: 1/2 inch, 3/4 inch, and 1-1/2 inch
- Stop collar window aligns with the bit markings for simpler, repeatable setup
Keep One More Setup Ready
If you switch between material sizes or just do enough pocket-hole work to wear consumables out, a second Kreg setup saves time and keeps the jig working the way it should.
- Direct replacement for the drill bit, collar, and gauge included with several Kreg jig models
- Useful as a spare for shop work or as a dedicated setup for one material thickness
Check Material Thickness Before You Drill
Pocket-hole joints go wrong when the stock is not what you thought it was. The included gauge helps catch that before the first hole.
- Thickness gauge measures 1/2 inch, 3/4 inch, and 1-1/2 inch material
- Built-in hex wrench means the same tool used to check thickness also helps adjust the collar
