Drill bit Bosch CYL-3 8 mm x 120 mm, single piece

The Bosch CYL-3 8 mm x 120 mm single-piece drill bit is engineered for creating precise holes in concrete and other masonry materials. Constructed with a highly durable Bosch carbide blend, this 8 mm bit is intended for repeated use in demanding conditions and is compatible with cylindrical shank systems for corded and cordless impact drills. Its 120 mm length provides reach for standard installation and repair tasks while the 2-flute U-shape design supports efficient dust extraction and reduced wear during drilling.

Advantages

The specially developed carbide mix increases wear resistance and extends service life when drilling abrasive materials such as concrete and natural stone. The 2-flute U-shaped geometry improves dust removal from the hole, lowering friction and heat generation for more consistent drilling performance. The bit meets the masonry drill testing standards of the relevant association, ensuring tight tolerances, accurate hole formation and reliable anchoring for fixings.

Suitable for

• Drilling holes for wall anchors and fixings in concrete
• Installation of fixtures in masonry and natural stone
• General construction site drilling where an 8 mm hole is required
• Repair and renovation work involving limestone or artificial stone

How to use

Secure the drill bit in the drill chuck designed for cylindrical shanks, ensuring it is held firmly and aligned. Select an appropriate drilling mode and speed for masonry or hammer drilling depending on the drill. Position the bit at the marked point and start drilling with steady pressure—avoid excessive lateral force. Withdraw the bit periodically to clear dust if drilling deep holes. After drilling, clean the hole of debris before fitting anchors or fixings.

Usage recommendations

Use appropriate personal protective equipment such as safety goggles, dust mask and hearing protection. Match drill speed and impact settings to the material being drilled and allow the bit to cool between prolonged operations to maximize lifetime. Replace the bit when wear or loss of cutting performance affects hole accuracy or anchoring quality.
