Self-Centering Dowel Jig Kit
About this item
- Robust and Durable: Crafted from 6061-T5 aluminum alloy, CNC-machined, heat-treated, and anodized for enhanced durability and anti-corrosion resistance against wear.
- Precise Positioning: Drill guides in three specifications - 1/4", 5/16", and 3/8". High hardness and wear resistance ensure drilling at the accurate angle and depth with no deviations or gaps.
- Effortless Operation: The adjustable feet of the self-centering fixture can be tailored to material thickness. Adjusting the screws enables swift movement and continuous drilling.
- Versatile 2-in-1: Serves as both a self-centering jig for drilling and a center marking tool for accurate measurements and size annotations.
- Kit Includes: 1 self-centering jig, 3 drill guides (6mm / 1/4", 8mm / 5/16", 10mm / 3/8").
- Broad Applications: Ideal for DIY woodworking, drilling tasks, and carpentry. A great tool for woodworking enthusiasts, construction workers, and carpenters.
Fitment & clearance
Independently tested, not just claimed
Anyone can print "aircraft-grade aluminium" on a listing. We had ours tested by SGS, an independent laboratory, and we publish the report numbers so you can ask for them.
| Series | SGS report | Date | Result |
|---|---|---|---|
| STING | KK-25-09211A | 13 Sep 2025 | A6061-T6 composition verified · 46.0% IACS |
| Eagle | KK-26-04498 | 05 Jun 2026 | 48.0% IACS |
| FLEX | KK-26-04499 | 05 Jun 2026 | 46.7% IACS |
Electrical conductivity tested to ASTM E1004-23; IACS is the standard scale for how well a metal conducts. The aluminium is separately tensile tested to ASTM B557-15 — 52 ksi tensile, 50 ksi yield, against 6061-T6 specification minimums of 38 and 35. Machined and tested in Taiwan.

Coming: Battery Terminal Fitment & Torque Guide
Post identification chart, the four measurements to take in your own engine bay, torque table, and a print-to-scale paper template you can hold against your battery before you order. Body dimensions are already published in the dimension table.
We are still measuring — every dimension in the guide is taken off the actual product rather than a drawing, and we would rather publish it late than publish a number we have not verified. There is no signup form here yet because we have nothing to send you yet. When the guide is ready this box becomes the place to get it.
