YS1
Premium Thin-Wall Core Bit
SHIBUYA YS1 Diamond Core Bit Series
The SHIBUYA YS1 Diamond Core Bit Series is a premium one-piece thin-wall diamond core bit engineered for high-performance wet concrete coring applications. Manufactured in Japan, the YS1 series is designed to deliver fast drilling speed, smooth operation, excellent hole accuracy, and long service life across a wide range of concrete conditions.
Featuring a lightweight thin-wall barrel design, the YS1 reduces drilling resistance while improving penetration speed and overall drilling efficiency. The high-quality diamond segments provide consistent cutting performance in concrete, reinforced concrete, and various construction materials, making it a preferred choice for professional contractors and coring specialists.
To achieve optimum performance under different job site conditions, the YS1 series is available in three specialized bond types:
Soft Bond (Blue)
Designed for hard concrete, high-strength reinforced concrete, and dense aggregate materials. Provides faster diamond exposure and helps maintain cutting speed in difficult drilling conditions.
Medium Bond (Black)
A balanced general-purpose bond suitable for most daily concrete coring applications. Offers an excellent combination of cutting speed and lifespan.
Hard Bond (Silver)
Designed for abrasive concrete, green concrete, and softer building materials. Improves segment durability and extends core bit lifespan under abrasive drilling conditions.
