Concrete & Reinforced Concrete Core Bit Diamond Segments for Retipping & OEM
Concrete & Rebar · Retipping & OEM · Custom Formula · Multiple Segment Designs · Professional Coring
Alskar Concrete & Reinforced Concrete Core Bit Diamond Segments are engineered for professional core bit retipping and OEM manufacturing. Available in multiple segment geometries and application-specific bond formulations, the series can be matched to core bit diameter, concrete hardness, aggregate type, reinforcement level and drilling machine power. From standard concrete to heavily reinforced structural applications, Alskar segment systems are designed to balance drilling speed, diamond exposure and dependable service life.
1. Professional Core Bit Retipping System
The Alskar Core Bit Diamond Segment Series is designed for retipping reusable core bit barrels and for OEM production of new diamond core bits.
Unlike complete core bits, replacement segments need to be matched to much more than diameter alone. Correct segment selection depends on:
Core Bit Diameter
Barrel Wall Thickness
Concrete Hardness
Aggregate Type
Rebar Content
Drilling Machine Power
Wet / Dry Drilling Method
Required Speed vs. Life
2. Global Market Size Range
Core Bit Diameter: 25–300mm Standard Range
Larger Diameters: Custom Available
3. Segment Geometry Options
- Rectangular
- Roof
- Turbo
- Turbo + Roof
- Crown
- Dimple
- Mesh Roof
- Patterned / Ordered Diamond
- Great Wall / Zigzag
| Segment Design | Alskar 定位 |
|---|---|
| Standard Flat Segment | General concrete / value |
| Roof-Top Segment | Fast start / easier centering |
| Turbo / Turbo Roof Segment | Faster drilling / improved slurry evacuation |
| Dimpled / Patterned Segment | Improved opening / controlled diamond exposure |
| Precision Diamond Segment | Premium reinforced concrete / highest performance |
4. Roof-Top Segment
The roof-top profile reduces the initial contact area during drilling, helping the bit start more easily and establish the drilling path before the segment wears into its normal working profile.
Design for:
General Concrete
Reinforced Concrete
Professional Retipping
5. Turbo / Turbo Roof Segment
Fast Drilling / Improved Slurry Removal
Turbo grooves increase the active cutting edge and create additional paths for coolant and drilling slurry, supporting faster drilling and improved debris evacuation.
6. Dimpled / Patterned Segment
Patterned surface geometry helps improve initial diamond exposure and segment opening while supporting consistent drilling performance.
7. Precision Diamond Distribution
Precision Diamond Placement
Ordered Diamond Distribution
Design for:
Heavy Reinforcement
High Production
Premium Core Drilling
8. Application Formula System
| Formula | Positioning |
|---|---|
| C1 — General Concrete | Balanced speed and life for normal cured concrete |
| C2 — Reinforced Concrete | Designed for regular reinforcement levels |
| C3 — Heavy Reinforcement | Higher-performance formula for dense rebar conditions |
| C4 — Hard Aggregate | Designed to maintain diamond exposure in dense hard aggregate |
9. Segment Height
9 / 10 / 12mm Standard Options
15mm Extended-Life Custom Option
10. Segment Length & Width
Typical Segment Length
23 / 24mm
Width
Size-specific — matched to barrel diameter and wall thickness
11. Standard Reference Platform
| Core Bit Diameter | Typical Segment Length | Typical Width Range | Height Options |
|---|---|---|---|
| 25–52mm | 20–23mm | ~3.0–3.5mm | 9 / 10mm |
| 62–82mm | 23–24mm | ~3.5–4.0mm | 9 / 10 / 12mm |
| 92–127mm | 23–24mm | ~3.8–4.0mm | 9 / 10 / 12mm |
| 132–182mm | 24mm | ~3.8–4.2mm | 10 / 12mm |
| 200–250mm | 24mm | ~4.0–4.5mm | 10 / 12mm |
| 300mm+ | Custom | Custom | 10 / 12 / Custom |
Final segment size must be matched to the core bit barrel design, wall thickness and required side clearance.
