Stainless steel drill sleeves (6 / 8 / 10 / 14 mm) — precision guides for accurate, repeatable holes in aluminum profiles, woodworking and metalworking. Key benefits Accurate hole placement: Prevent drillbit drift and reduce wobble so holes are placed exactly where you need them. Consistent results: Hardened stainless steel construction holds its shape under repeated use for uniform hole size and alignment. Versatile sizes: Includes 6 mm, 8 mm, 10 mm and 14 mm sleeves to match common drillbit diameters and project requirements. Easy to use: Fits standard drills and is suitable for both professionals and DIY enthusiasts to speed up repetitive drilling tasks. What it solves Eliminates misaligned holes that cause poor fit, weak joints or rework. Reduces material damage from wandering bits, especially on thinwalled aluminum profiles. Cuts setup time by providing a simple reusable guide instead of complex jigs. Key attributes Function: Drill guide sleeves that stabilize the drill bit and control entry angle and position. Compatibility: Designed for aluminum profiles and suitable for general woodworking and metalworking applications. Material: Durable stainless steel resists wear, bending and corrosion for long service life. Performance: Maintains concentricity and reduces vibration for cleaner, more accurate holes. Typical applications Assembling Tslot or extrusion aluminum frames where precise hole alignment is required for connectors and fasteners. Drilling mounting holes for hinges, brackets and hardware on aluminum window/door profiles or enclosure panels. Creating precise dowel or bolt holes in wood or lightgauge metal parts for furniture or fixture assembly. Includes Four stainless steel drill sleeves in sizes 6 mm, 8 mm, 10 mm and 14 mm. Who it's for Professionals installing aluminum profiles or fabricating metal/wood assemblies. DIY enthusiasts who want repeatable, accurate drilling without complex fixtures. Durability and care Built from stainless steel for repeated use; clean and store dry to maintain performance.
