The system uses a 9.5 mm bit, also designated 3/8″. The cutting edge wears with regular drilling, so the second bit can serve as a spare while you work.
Why an ordinary drill bit is not enough
A stepped bit creates a pocket hole for a screw: a wider pocket with a seating surface for the screw head and a narrower pilot hole. An ordinary drill bit of the same diameter cannot create that shape in a single pass.
Diameter is only one consideration when choosing a replacement. Jigs can also differ in the required bit length, pilot tip shape and stop collar position. A bit made specifically for the XK4 is therefore the safest choice. The 3/8″ measurement is exactly 9.525 mm; 9.5 mm is a rounded designation.
Set the stop collar for the material
The stop collar on the bit determines how deeply it passes through the jig into the material. Drilling too deeply can break through the material; drilling too shallowly will leave the pocket at the wrong depth.
Set both the collar position and the jig according to the material thickness and the instructions in the XK4 manual. Check the setting again after replacing the bit, and drill a test hole in a scrap piece of the same thickness before working on the finished part.
Material thickness and screw selection
XK4 documentation gives an approximate material thickness range of 12–42 mm. The bit stays the same, but the jig setting, drilling depth and suitable screw length change with the thickness of the workpiece. Choose the screw length using the manual’s guidance for the specific thickness; the correct bit alone does not guarantee a properly made joint.
Chips, overheating and wear
Drilling a pocket hole produces a lot of chips. If the bit advances too quickly and its flutes clog, chip removal becomes less effective and the bit can overheat. Drilling gradually and briefly withdrawing the bit helps clear the chips. The XK4 has a chip and dust removal system that helps clear them from the drilling area.
Greater resistance while drilling, a rougher hole surface or burn marks on the wood can indicate a dull or overheated cutting edge. Check the bit and chip removal, and replace the bit if it is damaged or dull.
When a two-pack makes sense
For an XK4 owner, a second bit is a useful spare, particularly when drilling a series of holes. If the bit in use becomes dull or damaged, it can be replaced so work can continue. Check the stop collar position again before drilling with the replacement.
