HITACHI double‑cut SDS‑Plus drill bit 10 x 310 mm

HITACHI double‑cut SDS‑Plus drill bit 10 x 310 mm is a rotary and hammer‑drill bit engineered for drilling into concrete, masonry and natural stone. With a 10 mm diameter and 310 mm overall length, this SDS‑Plus shank bit is intended for deeper holes and repeated use in installation and demolition tasks. The double‑cut tip reduces clogging, enhances chip evacuation and supports faster drilling progress in dense materials.

Advantages

The double‑cut tip design provides improved cutting efficiency and cleaner hole edges compared with single‑cut points. The SDS‑Plus shank ensures secure retention in compatible hammer drills and allows quick bit changes. The length accommodates deeper penetration without the need for extension, while the balanced flute geometry promotes reliable dust and debris removal during operation.

Suitable for

• Drilling holes for anchors and fasteners in concrete and masonry
• Installation of plumbing, electrical conduit and HVAC mounts
• General demolition and retrofit work requiring repeated deep holes
• Drilling in natural stone for construction and repair tasks

Key specifications

• Diameter: 10 mm
• Overall length: 310 mm
• Shank type: SDS‑Plus
• Tip: double‑cut (two‑edged) for improved chip removal
• Intended materials: concrete, masonry, stone

How to use

Install the drill bit into an SDS‑Plus compatible hammer drill according to the drill manufacturer’s instructions, ensuring the shank locks securely. Select the hammer‑drill mode when penetrating concrete or masonry, and apply steady axial pressure without excessive force to allow the bit’s tip geometry to cleave material effectively. Withdraw the bit occasionally to clear debris from the hole and prevent overheating. For through‑holes or long drilling sequences, use appropriate dust extraction or personal protective equipment.

Usage recommendations

Use the 10 x 310 mm bit for anchor and fixture holes where depth and consistent performance are required; match drill speed and hammer action to material hardness and replace the bit when wear causes reduced drilling speed or poor chip evacuation.
