Bosch 1 617 000 117 pora porasarja 1, 3

The Bosch 1 617 000 117 drill bit set contains three SDS-plus compatible masonry drill bits with a working length of 165 mm and diameters of 6 mm, 8 mm and 10 mm. Designed for use with rotary hammers, the set provides consistent hole quality in concrete, brick and stone. The geometry and material treatment of the bits are intended to deliver wear resistance and stable drilling performance across repeated applications.

Advantages

The drill bits are constructed for improved durability and precise drilling depth control in hammer drilling applications. Their carbide tips and reinforced shank geometry reduce breakage risk and maintain drilling momentum in medium to hard masonry. Standardized shank design ensures quick, secure fitting into SDS-plus chucks and ease of bit changes on compatible rotary hammers.

Suitable for

• Drilling holes in concrete and reinforced concrete for anchors and dowels
• Creating openings in brick and natural stone for installation work
• Professional and DIY hammer drilling tasks requiring 165 mm bit length

Key specifications

• Bit type: SDS-plus rotary hammer masonry bits
• Working length: 165 mm
• Diameters included: 6 mm, 8 mm, 10 mm
• Tip material: carbide-tipped for masonry applications
• Suitable materials: concrete, brick, natural stone

How to use

Select the appropriately sized bit for the required hole diameter and insert it fully into an SDS-plus rotary hammer chuck until it locks. Use the rotary hammer in hammer drilling mode, applying steady axial pressure while maintaining the tool perpendicular to the work surface. Begin drilling at low speed for positioning, then operate at the recommended speed and feed rate for the material being drilled. Withdraw the bit periodically to clear dust and debris for more efficient cutting and to reduce heat build-up. After use, clean the bit and store it in a dry place to prevent corrosion.

Recommendations

Use appropriate personal protective equipment—safety glasses, hearing protection and a dust mask—when drilling masonry. Match drill diameter to anchor or dowel size and verify that the rotary hammer supports SDS-plus bits and the 165 mm working length for safe, reliable operation.
