Kreg Pocket Hole Jig 310

The Kreg 310 brings hardened-steel drill guide precision and preset thickness stops to the entry-level market, solving the pocket hole accuracy problem for contractors who don’t need high-production features. This single-drill-guide system handles 1/2”, 3/4”, and 1-1/2” materials — the exact dimensions filling Montana lumberyards.

This jig shines for jobsite repairs, tight-space work, and contractors who pocket hole occasionally rather than constantly. The portable design and twist-apart capability for expandable setups matters when you’re fixing cabinets in cramped kitchens or building custom shelving on-site.

Core Specifications and Material Compatibility

The 310 features a durable impact-resistant polymer body wrapped around a hardened-steel drill guide with lifetime warranty. That steel guide maintains the critical 3/8-inch (9mm) diameter hole that pocket screws demand for proper strength.

Specification	Value
Drill guide diameter	3/8 inch (9mm)
Material thickness capacity	1/2 inch to 1-1/2 inch (13mm to 38mm)
Preset thickness stops	1/2”, 3/4”, 1-1/2”
Pocket hole spacing	Variable (User-positioned single drill guide system)
Construction	Impact-resistant polymer body, hardened-steel guide
Drill bit type	Easy-Set with etched markings and stop collar window

The removable thickness stops for 1/2”, 3/4”, and 1-1/2” materials match the plywood and dimensional lumber stacked at every Montana yard. No fiddling with measurements — snap in the right stop and drill. The Easy-Set drill bit includes etched markings and a stop collar with viewing window, eliminating the guesswork that ruins pocket holes.

Jobsite Performance and Portability

The single-drill-guide design excels for on-the-go projects and tight spaces. Unlike benchtop jigs that demand setup space, the 310 works wherever you can clamp it. The GripMaxx anti-slip base holds position without excessive clamping pressure — critical when you’re balancing on a ladder fixing upper cabinets.

Setup follows a straightforward sequence: measure material thickness, adjust the stop, set the collar on the bit, clamp the jig, and drill. The system’s compatible with all standard Kreg pocket-hole screws and plugs, plus accessories like the 300-Series Expansion Pack for wider panels.

The twist-apart design connects with other 300-series guides for contractors who occasionally need multi-hole capacity. Buy additional 310 units and link them for production-style drilling when the job demands it. The compact size matters for existing furniture repairs where traditional benchtop jigs simply won’t fit.

FAQ

What materials can the Kreg 310 handle? The jig accommodates materials from 1/2 inch to 1-1/2 inch thick (13mm to 38mm), with preset stops for 1/2”, 3/4”, and 1-1/2” thicknesses. This covers standard plywood, 1x boards, and 2x dimensional lumber.

Does the plastic construction affect accuracy? The critical component — the drill guide — uses hardened steel with a lifetime warranty. While the body uses impact-resistant polymer, user reviews rate it 4.4-4.5 out of 5 stars for accuracy and clean pocket holes.

How does the 310 compare to multi-hole jigs for production work? The single-drill-guide system means repositioning between holes, making it slower for high-production projects. For occasional pocket holes or jobsite repairs, the portable design and compact form factor offset the speed disadvantage.

What’s included with the jig? The kit includes the drill guide with thickness stop, Easy-Set drill bit and stop collar, material thickness gauge that doubles as a hex wrench, 6-inch square-drive bit, and owner’s manual.

Can multiple 310 jigs work together? Yes — the twist-apart design allows connecting multiple 300-series guides for expandable setups. This lets contractors scale up capability without buying a larger jig upfront.
