YATO YT-4230 hammer drill bits set, 5 pcs, 25 mm diameter

YATO YT-4230 is a set of five hammer drill bits with a 25 mm diameter, intended for use with rotary hammers and percussion drilling. Designed for tasks that require impact-assisted drilling, this set supplies multiple ready-to-use bits for drilling into concrete, masonry and other hard building materials. The bits are suitable as replacements or as a compact selection for on-site work in construction and renovation.

Advantages

The five-piece set provides immediate availability of spare or replacement bits to reduce downtime on the job. Each bit has a 25 mm diameter optimized for medium-to-large holes in concrete and masonry when used with a compatible hammer drill. The bits feature geometries and material selection suited for impact drilling, ensuring consistent drilling performance under repeated percussion loads. The uniform diameter across the set simplifies inventory and selection for tasks that require the same hole size.

Suitable for

• Drilling anchor holes in concrete and reinforced concrete
• Masonry drilling for block and brick fastening
• Installing pipes and conduits through walls
• Renovation and construction site drilling where percussion action is required

Key specifications

• Quantity: 5 pieces
• Tip diameter: 25 mm
• Intended tool type: rotary hammer / hammer drill with percussion function
• Application: concrete, masonry and other hard mineral materials
• Function: percussion drilling for anchor and through holes

How to use

Select a suitable hammer drill compatible with the bit shank type, secure the bit in the tool's chuck or SDS adapter according to the drill manufacturer instructions, and set the tool to the hammer or rotary hammer mode. Mark the drilling location, start at low speed to create a guide recess, then apply steady pressure and allow the tool's percussion action to advance the hole. Withdraw periodically to clear dust and reduce heat build-up. Replace bits when wear or loss of cutting performance is observed.

Usage recommendations

Use personal protective equipment including eye and hearing protection and a dust mask when drilling. Match drill speed and applied pressure to the material being drilled and follow the rotary hammer manufacturer's guidance for drill bit selection and maximum permissible drilling parameters.
