Core Bits Segments

Diamond Core Bit Segments Manufacturer

Corediam is a diamond segment manufacturer specializing in diamond core bit segments for concrete and reinforced concrete drilling. We supply core drill bit manufacturers, retipping workshops, diamond tool distributors and OEM customers with standard and custom segments.

Core bit segments are the cutting elements joined to the front edge of a core drill bit barrel. Unlike diamond saw blade segments, they come in several cutting profiles, such as Roof-top, Turbo and Shark, and each profile suits different drilling conditions.

Our range covers 10 segment profiles, with compatible core bit diameters from 25 mm to 400 mm depending on the model. You can order for new core bit production, retipping worn bits, or wholesale distribution. We also produce segments to your drawings, samples and formula requirements.

How to Choose Diamond Core Bit Segments

The same profile can be made with different diamond formulas, so choosing by shape alone may not give the drilling performance you expect. Match the segment to the material first, then confirm the formula and joining method.

Drilling MaterialSegment Types to ConsiderKey Selection Factors
ConcreteRoof-top, Turbo, Shark, Dimple, Great WallConcrete hardness, aggregate, drilling conditions
Reinforced ConcreteShark, Turbo, Roof-top, LightningSteel reinforcement, cutting requirements
AsphaltRoof-top and custom profilesAbrasiveness, bond wear
Brick and MasonryShark, Roof-top, Great Wall, LightningMaterial characteristics, cutting requirements
Natural StoneCrown, Shark and custom profilesStone type, hardness, required performance

To get an accurate recommendation, send us the material, reinforcement condition, core bit diameter, and whether you drill wet or dry.

Joining Methods: Sintering, Laser Welding and Brazing

Our core bit segments are made by sintering and joined to the barrel by laser welding, high-frequency brazing, or copper welding, depending on the model. The joining method must match your barrel and production process, so please tell us which one you use when you inquire.

Replacement Segments for Core Bit Retipping

Retipping segments must match the existing barrel and the original segment arrangement. Popular retipping profiles include Turbo, Roof-top and Shark. When you request replacement segments, send us:

  • Original core bit outside diameter

  • Existing segment profile

  • Segment length, width and height

  • Number of segments required

  • Drilling material

  • Existing joining method, if known

  • Photos or a sample of the original segment

Custom and OEM Diamond Core Bit Segments

Corediam produces custom segments to your drawings, samples and drilling requirements. You can customize:

  • Profile: Shark, Turbo, Roof-top, Crown, Dimple and other designs

  • Dimensions: length, width, height and thickness

  • Diamond formula and bond: matched to material hardness and abrasiveness

  • Quantity per bit: matched to your core bit design

  • Joining method: laser welding or brazing, matched to your barrel

For OEM projects, please send the drawing, core bit diameter, required dimensions, drilling material and estimated order quantity. Include any private-label branding or packaging requirements in your inquiry.

Before production, we confirm the approved drawing and specifications with you. Any special inspection or acceptance requirements should be agreed in advance.

Frequently Asked Questions

What types of diamond core bit segments does Corediam manufacture?

Dimple, Roof-top, Crown, Mesh Roof-top, Shark, Great Wall, Turbo, Dotted, Lightning and Array Pattern segments. Different profiles suit different core bit designs and drilling applications.

What is the difference between core bit segments and saw blade segments?

Core bit segments are made for the curved cutting edge of a core drill barrel and come in profiles such as Roof-top, Turbo and Shark. Saw blade segments are made for flat blades and use different shapes and formulas.

What is the difference between Shark, Turbo and Roof-top segments?

Shark segments have a pointed, serrated profile. Turbo segments have a grooved profile. Roof-top segments have a raised, tapered surface. The right choice depends on your core bit design, drilling material and cutting requirements.

Can you supply segments for core bit retipping?

Yes. Please provide the original core bit diameter, segment dimensions, profile, quantity and joining method. Photos or a sample of the original segment help us match it.

What core bit diameters are supported?

Our range covers 25 mm to 400 mm, depending on the model. The available diameters depend on the segment profile and configuration, so please confirm the diameter you need when requesting a quotation.

Can you manufacture segments according to our drawings?

Yes. Please send the technical drawing, segment dimensions, core bit diameter, drilling material and expected quantity.

Can you customize the diamond formula?

Yes. Please tell us the material being drilled, the reinforcement condition, and whether cutting speed or wear resistance is your priority.

Which joining methods are available?

Laser welding, high-frequency brazing and copper welding or brazing, depending on the segment model. The right method depends on the segment construction and your core bit barrel.

What is the difference between sintering and welding or brazing?

Sintering is how the diamond segment is made. Laser welding and brazing are how the finished segment is joined to the barrel. Choose the joining method that matches your barrel and production process.

Do you supply segments for both new core bit manufacturing and retipping?

Yes. For new manufacturing, send your core bit design and required segment specifications. For retipping, send the original segment dimensions, core bit diameter and reference photos.

Can you supply private-label diamond core bit segments?

Yes, OEM requirements can be reviewed against your drawings and agreed product specifications. Please include any branding, labeling or packaging requirements in your inquiry.
