What this product is Solid carbide (Hartmetall) drill bits with SDS-plus shank, length approx. 210 mm (8.27") Available diameters: 6 mm (0.24"), 8 mm (0.31"), 10 mm (0.39"), 12 mm (0.47"), 14 mm (0.55"), 16 mm (0.63") Key benefits — why you need this set Durable cutting edge: Carbide tips resist wear and hold a sharp edge longer than HSS for repeated use in hard materials. Secure, vibration-resistant fit: SDS-plus shank ensures fast bit changes and steady engagement in compatible rotary hammers. Consistent reach and depth: 210 mm overall length gives enough reach for through-holes and deeper anchor or fixing points. Versatile diameter range: Six common sizes cover most anchoring, fastening, and through-drilling jobs without changing tool types. Function and compatibility Designed for use in SDS-plus rotary hammers and hammer drills. Intended for drilling in masonry, concrete, brick, and similar hard building materials where a carbide tip is required. Works with standard anchor bolts, sleeve anchors, and wall plugs sized to the listed diameters. Performance highlights Carbide construction delivers reliable cutting performance and improved life under hammering action. SDS-plus retention reduces wobble and improves drilling accuracy, particularly when working with harder substrates. Standardized diameters provide predictable hole sizes for anchors and fixings. Practical use scenarios 1. Installing anchors and heavy-duty fixtures: Drill 10 mm or 12 mm holes in concrete to set expansion anchors for mounting brackets, railings, or machinery bases. 2. Electrical and plumbing rough-in: Use 6 mm and 8 mm bits to run conduits and fasten cable clips through brick or block during retrofit work. 3. Renovation and construction tasks: Create 14 mm or 16 mm through-holes for pipes or bolts when cutting into solid masonry walls. What to expect in use Insert into any SDS-plus rotary hammer, set to hammer or hammer/rotation mode as appropriate, and drill with steady pressure. Carbide tips perform best when cooling and debris removal are managed by intermittent withdrawal or using dust extraction where possible. Choose the bit diameter that matches your anchor or pipe outside diameter for a secure fit.
