The OX Spectrum Trade XL5 steps the 3-piece set up to five dry core drill bits: 38mm, 52mm, 65mm, 117mm and 127mm, all 150mm deep. The extra 65mm and 127mm cores cover jobs that the smaller kit can't handle on its own, most obviously 127mm for standard UK soil stacks and 65mm for larger gas service runs and combi boiler flue penetrations.

Turbo-segmented diamond tips run dry through brick, blockwork and concrete. The spiral-grooved barrel design pulls dust out of the cut as you drill, which keeps the bit cooler and the cutting speed consistent across a day's work. Everything sits in an aluminium carry case with the arbor, pilot drill and extension, so the kit is van-ready from the moment it lands on the bench.

Technical Specifications

Key Features

• Five essential core sizes - 38mm to 127mm covers the bulk of first-fix work, from back boxes through to soil stacks, without swapping to a separate bit for the big holes.
• Turbo diamond segments - faster cutting speed through brick and concrete than standard continuous-rim cores. Gets you through the wall quicker, saves the motor working unnecessarily hard.
• Spiral dust clearance - the grooved body design pulls swarf out of the cut as you drill, which stops the bit binding and keeps the diamond running cool. Longer tip life and more consistent speed through the cut.
• Complete kit in one case - arbor, pilot drill, and 250mm extension supplied, so you're not chasing adapters on the morning of the job.
• Aluminium case - solid protection for the cores in transit. Keeps the diamonds sharp between jobs and stops the bits knocking each other dull in the van.

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 the 117mm and 127mm cores, use a purpose-built core drilling machine or a large rotary drill with a suitable side handle.
