Set di punte Bosch CYL-3 da 35 pezzi punte per calcestruzzo Extra Hard in valigetta KS

Bosch CYL‑3 35-piece concrete drill bit set Extra Hard in KS cassette is a comprehensive assortment of masonry and concrete drill bits designed for rotary and hammer drilling. The set contains a range of diameters suited to common anchoring, fixture and through-hole tasks. Bits are manufactured to Extra Hard grade to provide improved wear resistance and a consistent drilling feel when working with concrete, block and similar materials. A KS cassette keeps the bits organized for easy transport and safe storage.

Advantages

The Extra Hard grade carbide tips increase resistance to edge chipping and prolong bit life under repeated hammering in concrete. Precision ground flutes and reinforced shanks promote efficient dust removal and secure seating in chucks and tool holders. The KS cassette offers molded slots for each diameter to reduce bit movement during transport and to simplify selection on the job. The combination of varied diameters and durable construction makes the set suitable for frequent use in demanding environments.

Suitable for

• Drilling holes in concrete and masonry for anchors and bolts
• Preparing anchor points for electrical boxes and plumbing fixtures
• Installing wall-mounted hardware and structural fasteners
• General construction and renovation tasks requiring hammer or rotary-hammer tools

Key specifications

• Contents: 35 concrete drill bits in a range of common diameters
• Tip material grade: Extra Hard carbide for improved wear resistance
• Intended materials: concrete, masonry, block
• Shank type: standard SDS-plus or round shanks compatible with hammer and rotary-hammer tools (as per bit model)
• Storage: KS cassette with molded bit slots for organization and transport

How to use

Select the correct diameter for the required anchor or fixture and install the bit securely in the tool chuck or holder. Use the hammer or rotary-hammer mode for drilling into concrete and masonry to allow the tip to penetrate efficiently. Apply steady pressure without forcing the bit; allow the tool's percussive action to do the work. Withdraw the bit periodically to clear dust from the hole and maintain drilling speed. After use, clean the bits and return them to their molded positions in the KS cassette for storage.

Recommendations

For consistent hole quality, mark the drilling depth in advance and use a depth stop if available. Wear appropriate personal protective equipment such as eye protection, hearing protection and a dust mask when drilling concrete. Match bit diameter to anchor manufacturer recommendations and avoid excessive side-loading to prolong bit life.
