SD3 Diamond Bit
SHIBUYA® 3 Piece Type Small Diameter Core Bit Made in Japan
Shibuya SD3 Series – 3-Piece Type Small Diameter Core Bit (20mm – 45mm) – Made in Japan
The Shibuya SD3 Series Diamond Core Bit is a 3-piece modular core bit system, specifically designed for small-diameter coring applications ranging from 20mm to 45mm. Manufactured in Japan, this series features an A-Rod thread connection, making it compatible with A-Rod spindle core drills. The modular design allows for cost-effective part replacement and extendable deep coring by adding additional T-Part (Tube) sections.
Key Features & Benefits:
✅ 3-Piece Modular Design for Easy Replacement & Versatility –
🔹 Composed of three interchangeable parts:
✔ A-Part (Adaptor) – Connects to the drill spindle.
✔ T-Part (Tube) – Determines the coring depth and can be extended.
✔ B-Part (Bit Head) – The cutting tip with diamond segments.
🔹 Users only need to replace the B-Part (cutting head) when worn out, reducing costs.
✅ Extendable Depth for Deep Coring –
🔹 The T-Part (Tube) can be added to extend the drilling depth, making it ideal for deep coring applications.
🔹 Ensures flexibility for various coring depths without requiring a new core bit.
✅ A-Rod Thread Connection – Compatible with A-Rod Spindle Core Drills –
🔹 Designed specifically for A-Rod spindle connections, ensuring a secure fit and reliable drilling performance.
🔹 Works with Shibuya handheld and rig-mounted core drills using A-Rod threads.
✅ Small-Diameter Coring (20mm – 45mm) –
🔹 Ideal for anchor bolt installations, conduit openings, HVAC, and utility coring.
🔹 Provides clean and precise holes with minimal chipping.
✅ Premium Synthetic Diamond Segments for Fast Cutting –
🔹 Ensures high-speed cutting performance with superior wear resistance.
🔹 Designed for wet drilling, reducing friction and heat buildup.
✅ Lightweight & Strong Steel Core for Stability –
🔹 Made from high-strength steel, ensuring low vibration and accurate coring results.
