The OX Spectrum Trade XL3 is a three-core dry drilling kit covering the holes you actually cut on a domestic job: 38mm for back boxes and waste pipes, 52mm for soil stacks and vents, 117mm for large extractor fan outlets. Diamond tips with turbo segments chew through brick, blockwork, and concrete without needing water, and the spiral-grooved body shifts dust out of the cut as you go, which keeps the bit running cooler and the cutting speed consistent all the way through.

The aluminium case keeps everything together in the van and protects the diamond tips between jobs. Supplied as a complete kit with the arbor, pilot drill, and extension, so you're drilling on day one without a trip back to the merchant for adapters.

Technical Specifications

Key Features

• Turbo diamond segments - faster cutting speed through brick and concrete compared with standard continuous-rim cores. Less time per hole on a busy first-fix day.
• Spiral dust clearance - the grooved body pulls swarf out of the cut, which stops the bit binding and keeps the diamond running cooler. That translates directly into longer tip life.
• Three common sizes covered - 38mm handles back boxes and small wastes, 52mm handles soil and vent, 117mm handles large extractor outlets. The three holes most first-fix jobs need.
• Complete kit in one case - arbor, pilot drill, and extension supplied, so no hunting for adapters before you start drilling.
• Aluminium case - sturdier than a plastic box, keeps the tips protected in the van and stops them knocking each other dull in transit.

Usage notes: Rotary use only. Do not run on percussion or hammer mode. Do not use diamond cores larger than 78mm with SDS-plus drills, as this can damage the drill or adapter. For 117mm cutting, use a purpose-built core drilling machine or large rotary drill.
