• Wet-only performance – Water cooling improves edge quality, lowers heat, and significantly extends service life.
• High-frequency welded segments – Strong, consistent joints for reliable cutting in dense, silica-rich materials.
• Rebar-capable coring – Designed for reinforced concrete; feed and speed must be adjusted when encountering rebar.
• Universal thread options – M22, 1-1/4" UNC, 1/2" GAS for wide machine compatibility.
• Wide size coverage – Standard Ø18–350 mm diameters and 370–450 mm lengths; special sizes on request.
• Clean, round holes – Rigid carbon-steel barrel controls runout for accurate sleeves, anchors and service penetrations.
• OEM/ODM ready – Custom diameters, bonds, colors, logos, labels and packaging for your market.
Usage Scenarios
• MEP penetrations – Clean openings for pipes, conduits, and sleeves through slabs and walls.
• Anchoring & fastening – Round holes for chemical anchors and through-bolts with controlled edge chipping.
• Renovation & retrofits – Precision coring in structural and partition elements.
• Stone & hard brick – Reliable cutting with water cooling for sharp edges and smoother finishes.
• 1-1/4" UNC (7 TPI) – Common on many professional coring rigs worldwide.
• M22 – Frequent in regional hand-held and rig systems.
• 1/2" GAS (G1/2) – Broadly used in core-bit adapters and certain drill platforms.
Select the thread to match your drill spindle or adapter. If unsure, share your drill model for confirmation.
• Always run wet – Ensure steady water flow to the rim; never start the cut dry.
• Rotation-only – Do not use hammer/percussion; it damages segments and increases edge spalling.
• Start square & light – Establish the kerf, then increase feed; periodically lift to clear swarf.
• Through rebar – Reduce feed and maintain coolant; avoid binding. If heavy rebar density is expected, request a tougher bond.
• Dress when needed – If progress slows, dress the rim on an abrasive block to expose fresh diamonds.
As a dedicated diamond tools manufacturer, SENMINE delivers stable bond quality, tight concentricity, and repeatable batches for distributors and project contractors. We support:
• Custom sizes, bonds, and thread standards
• Private label & packaging programs
• Flexible MOQs (typically 10 pcs per size) and reliable lead times
• Technical guidance on bit selection and rig setup
• Can this bit cut through rebar?
Yes—this model is intended for reinforced concrete. Reduce feed, keep coolant flowing, and expect slower progress at the bar. For very dense reinforcement, ask us for a rebar-optimized bond.
• Can I use it dry?
No. This is a wet-only core bit; running dry will overheat and glaze the rim.
• What RPM should I use?
Follow your rig manufacturer’s chart for the selected diameter. Lower RPM for larger diameters; maintain steady feed with active cooling.
• Hand-held or rig-mounted?
Both are supported. For large diameters or overhead work, a rig-mounted setup is recommended for accuracy and safety.
• Do you offer OEM colors and branding?
Yes—custom colors, laser marking, labels, and cartons are available to match your brand.
