Key benefits Accurate, repeatable 90 degree holes: the straight guide keeps your drill perfectly perpendicular to the workpiece, eliminating angled or crooked holes. Consistent depth control: double guide rails with springs let you set and maintain drilling depth for uniform results across multiple holes. Robust build for jobsite use: steel construction and a solid aluminium alloy base deliver long-term durability and stable performance. Broad compatibility: includes a 1.13 mm drill chuck and fits all 3/8 inch and 1/2 inch drills, so it works with common handheld drills without extra adapters. Safer, easier handling: the unit is equipped with 1 non-slip handle to improve grip and reduce slippage during operation. Features (what it does) 1.13 mm drill chuck included for immediate use with fine bits. Straight guide for precise 90 degree drilling. Double guide rails with springs for adjustable, controlled depth. Steel construction with a solid aluminium alloy base for strength and stability. Compatible with all 3/8 inch and 1/2 inch drills. How this solves common problems Prevents misaligned holes that cause parts to bind or assemblies to fail. Eliminates inconsistent hole depths that lead to weak fastenings or rework. Reduces bit wobble and movement, protecting both the bit and the work surface. Speeds up repetitive drilling tasks by providing a stable guide and repeatable stops. Practical use scenarios Cabinet and furniture installation: drill perfectly square pilot holes for hinges and fasteners with consistent depth for flush fittings. On-site carpentry and trim work: use with a 3/8 inch or 1/2 inch handheld drill to quickly create accurate, repeatable holes in wood or composite materials. Small metal or plastic fabrication: maintain precise hole placement and depth when mounting brackets or assembling panels. What’s included 1.13 mm drill chuck (included).
