Boor Bosch SDS plus-7X 4 mm diameter 115 mm lengte

EXPERT SDS plus-7X Hammer Bits for rotary hammer drills, Bosch 4 mm diameter, 115 mm length. The EXPERT SDS plus-7X is engineered for long life drilling in reinforced concrete and hard stone. It features a Full Carbide Head with four cutting edges and Bosch Carbide Technology for improved wear resistance, together with a robust welded tip connection designed to withstand heavy impact and reduce breakage compared with standard two-cutter bits.

Advantages

The Full Carbide Head is manufactured from a single piece of carbide for high impact strength and reduced risk of jamming in rebar. Bosch Carbide Technology increases tip durability for up to three times longer life versus standard drill bits. A reinforced, welded tip connection improves resistance to tip failure under repeated hammering.

Suitable for

• Drilling holes in cured concrete
• Drilling hardened reinforced concrete
• Drilling hard natural stone such as granite and gneiss
• Use with SDS plus rotary hammer drills for fixings and installations

How to use

Fit the 4 mm EXPERT SDS plus-7X bit into an SDS plus rotary hammer drill according to the drill manufacturer's instructions. Start drilling at low speed to position the bit, then apply steady pressure and use the hammer function for reinforced concrete or hard stone. Withdraw the bit periodically to clear debris and avoid overheating. Replace the bit when wear affects cutting performance.

Recommendations

Use appropriate personal protective equipment (safety glasses, gloves and hearing protection) and follow site safety rules. Select the correct drill and operating mode for the material. For prolonged jobs in reinforced concrete, check the bit regularly and replace when the cutting edges are worn to maintain performance.
