Drill Bit Bosch SDS plus 5X 4x50x110 mm for rotary hammers, model 2608836604

The Bosch SDS plus 5X drill bit 4x50x110 mm is a rotary-hammer accessory designed for drilling small-diameter holes in concrete, brick and natural stone. With a 4 mm diameter, a 50 mm working length and a total length of 110 mm, this bit fits SDS plus chucks and is intended for routine masonry tasks such as making holes for anchors, dowels and light fixtures. The carbide tip and reinforced flute geometry provide focused impact transfer for efficient penetration in hard substrates.

Advantages

This SDS plus 5X bit combines a compact 4 mm diameter with a longer overall length to reach recessed or deep-set fixing points while maintaining stability in rotary-hammer operation. Its carbide cutting tip ensures clean entry and reliable centring, and the flute design removes dust effectively to maintain drilling progress. The SDS plus shank allows quick bit changes and secure retention in compatible rotary hammers.

Suitable for

• Drilling 4 mm holes in concrete for light anchors and dowels
• Preparing fixing points in brick and masonry for electrical boxes and fixtures
• Repair and maintenance work where precise, small-diameter holes are required

How to use

Fit the drill bit into an SDS plus rotary hammer according to the tool manufacturer's instructions and secure it in the chuck. Select an appropriate hammer or rotary-hammer setting for masonry drilling. Mark the drilling point and start at low speed to establish the hole, then apply steady pressure and increase power as needed while allowing the tool to do the work. Periodically withdraw the bit to clear debris and prevent binding; use dust extraction or a brush to keep the hole clean.

Usage recommendations

Use personal protective equipment such as safety glasses, gloves and hearing protection. For optimal performance, match the drill mode and power setting of the rotary hammer to the material being drilled and replace worn bits to maintain clean drilling and accurate hole dimensions.
