Dry Diamond Core Bit with SDS Max Pilot Bit Adapter

When water is restricted or interior finishes must stay clean, dry coring is often the smartest choice. This set pairs a dry diamond core bit with an SDS Max pilot bit adapter so you can run it directly on an SDS Max core drill in rotation-only mode. The pilot bit stabilizes the start, the dry-optimized diamond matrix resists glazing at higher temperatures, and the rigid steel barrel keeps runout low—so electricians, plumbers, HVAC crews, and general contractors get round, accurate holes with less rework. As a factory manufacturer and supplier, SENMINE supports distributor programs, private label, and custom specifications to fit your local market.

Key Features & Benefits

• Built for SDS Max core drills – Threaded core barrel pairs with our SDS Max pilot adapter for secure drive on SDS Max core drill spindles; use rotation-only (no percussion) to protect segments and edge quality.
• Pilot-guided starts – Replaceable pilot bit centers the barrel, reduces walking on smooth concrete or tile, and improves hole roundness—especially on large diameters.
• Dry-optimized diamond segments – Formulated for heat resistance and steady self-sharpening under dry conditions; optional high-abrasive aggregates and rebar-tolerant bonds available.
• Rigid alloy steel core – Low runout, smoother feed, and less vibration for cleaner edges and lower operator fatigue.
• Size coverage for MEP tasks – Common trade diameters stocked; custom sizes, lengths, and threads available to match regional standards and your fleet.
• OEM & branding options – Laser mark, color spray, and packaging customization to streamline your inventory and retail presentation.

How the SDS Max Pilot Bit Adapter Works

The adapter locks into your SDS Max core drill via its SDS Max shank. The threaded end mates with the core barrel (1-1/4"-7 or M16). A centered pilot bit sits slightly ahead of the diamond rim. As you start the hole in rotation-only mode, the pilot establishes a guide path and stabilizes the barrel. Once the diamond rim engages, guidance from the pilot suppresses vibration and side-walk, improving accuracy and finish. When worn, the pilot bit can be replaced independently—cutting consumable costs while keeping the barrel in service.

Recommended Applications

• Electrical & low-voltage – Conduit pass-throughs, junction access holes, and sleeve openings in interior walls.
• Plumbing & HVAC – Water/gas lines, condensate, and vent penetrations in concrete or masonry where wet slurry isn’t acceptable.
• Renovation & occupied sites – Hospitals, retail, schools, and offices that require dry methods with dust control.
• Anchoring & fixings – Clean, round holes for chemical anchors and through-bolts where edge integrity matters.

Selection Tips (Quick Guide)

• Match diameter to fitting – Allow clearance for sleeves, insulation, and sealants to avoid post-drill grinding.
• Pick the right bond – Hard bond for abrasive block/lightweight concrete; medium bond for standard concrete; tougher bond for harder aggregates or intermittent rebar contact.
• Plan dust control – Use a compatible dust shroud and high-CFM vacuum to protect operators and maintain cutting speed.
• Use correct mode – Rotation-only on your SDS Max core drill. Avoid impact to protect the segment rim and reduce chipping.
• Mind the temperature – Pulse the feed and clear swarf periodically; if the rim glazes, dress lightly and resume.

Why Work with SENMINE

FAQs

• Can I run this on a rotary hammer?
Use an SDS Max core drill or a rotary hammer specifically rated for core drilling in rotation-only mode. Do not use percussion; impact can damage segments and increase chipping.

• How does it handle rebar?
Light, intermittent rebar contact is possible, but speed and life depend on rebar size and density. For heavy reinforcement or large-diameter continuous coring, wet coring is recommended.

• What dust extraction do I need?
Pair the bit with a tight-fitting dust shroud and a high-efficiency vacuum. Good extraction maintains visibility, protects operators, and keeps the rim cutting instead of polishing.

• Can I buy the core barrel, adapter, and pilot separately?
Yes—order complete sets or individual components to simplify service and stocking.

• Do you offer OEM colors and packaging?
Absolutely—barrel color, markings, labels, and cartons can be branded to your program.
