25-356mm

Dinosaw diamond segments for core drill bits cover HVAC openings, structural coring, utility pass‑throughs, asphalt sampling and small‑diameter porcelain/ceramic coring. For concrete, reinforced concrete, masonry/brick and asphalt, crowns balance speed, swarf evacuation and durability. Optimized bonds and grit deliver clean edges and smooth walls with lower Ra, while laser‑weldable geometry boosts reliability. ISO 9001 and CE verified.

DINOSAW diamond segments for core drill bits are replaceable cutting crowns for professional drilling fleets: material-class formulations across the 25–356 mm bit range, with segment sets that rebuild serviceable steel bodies instead of discarding complete bits.

Real Coring Performance & Key Metrics

Bit Diameter Program

Segment specifications follow the bit diameter ladder from 1" (25 mm) small-diameter bits to 14" (356 mm) structural coring bits — one program across the coring fleet.

Segment Count by Diameter

Segment count scales with bit diameter (3 segments at 25 mm to 12 at 152 mm and above): the crown maintains balanced cutting contact instead of loading a few oversized segments.

Standard Segment Height

The 10 mm standard height supports the crown's working life and the re-tipping cycle per bit body class.

Material-Class Bond Matching

Concrete, asphalt, masonry and vitrified materials wear diamond segments in different ways: DINOSAW selects bond hardness, diamond specification and segment geometry around aggregate abrasiveness, reinforcement content and drilling conditions — not from a simple hard-material/soft-material formula, because aggregate type and job conditions drive the wear regime.

Reinforced Concrete Toughness

Reinforced-concrete drilling repeatedly transitions between aggregate, cement matrix and steel: segment formulation and attachment must tolerate those changing loads without excessive diamond loss or segment damage — the crown earns its specification in those transitions.

Diameter-Scaled Crown Loading

Segment quantity and dimension scale with bit diameter so the crown maintains balanced cutting contact: even loading around the circumference keeps the hole round and the bit tracking straight through long cores.
