Adjustable Aluminum Drilling Positioning Guide with Marked Ruler and Stainless Steel Drill Sleeves

This drilling positioning guide is built from aluminum alloy with brass screws and stainless steel drill sleeves, combining a rigid frame with wear-resistant components. It uses a rectangular adjustable frame, ruler markings, and knurled adjustment knobs to help align drilling points on wood and furniture panels. The clamping guide structure supports cross and slant flat-head drilling layouts for accurate hole placement. It includes 5 stainless steel sleeves in 6 mm, 8 mm, 10 mm, 12 mm, and 15 mm sizes. Designed for accurate hole positioning and clean guidance, it improves consistency when working on panels.
