DeWalt DT9620 SDS‑EX2 rotary hammer drill bit 5 x 460/400 mm

DeWalt DT9620 SDS‑EX2 rotary hammer drill bit 5 x 460/400 mm is a carbide‑tipped masonry drill bit designed for use with SDS‑type rotary hammers. With a 5 mm diameter and an overall length of 460 mm (working length 400 mm), this bit provides extended reach for drilling deep holes in concrete, brick and other masonry materials. The SDS‑EX2 shank ensures secure tool retention and efficient power transfer when used with compatible hammer drills. The carbide tip is engineered to withstand high impact and abrasion for consistent drilling performance in demanding applications.

Advantages

The carbide‑tipped head delivers durable cutting performance and improved wear resistance compared with standard steel bits. The elongated overall and working length allows drilling deeper holes or reaching recessed areas without change of accessories. The SDS‑EX2 shank design provides secure fitment in rotary hammer chucks, reducing slippage and improving energy transmission from the tool to the bit. The product is suitable for repeated use in professional and DIY environments where consistent hole size and depth are required.

Suitable for

• Drilling through concrete for anchor and dowel holes
• Creating deep holes in masonry and brickwork
• Reaching recessed or hard-to-access drilling points
• Professional construction and renovation tasks requiring extended reach

Key specifications

• Shank type: SDS‑EX2 compatible
• Diameter: 5 mm
• Overall length: 460 mm
• Working length (effective drilling length): 400 mm
• Intended material: Concrete, masonry, brick
• Application: Rotary hammer drilling (impact drilling)

How to use

Select a compatible SDS‑type rotary hammer and secure the DT9620 bit in the chuck according to the tool manufacturer's instructions. Mark the drilling position, set the drill to the hammer mode, and start drilling at low speed to establish the hole. Apply steady pressure without forcing the bit; allow the hammer action and carbide tip to do the cutting. Periodically withdraw the bit to clear dust and debris and to prevent binding. For deep holes, check working depth regularly and cool the bit as required by the working conditions.

Usage recommendations

For best results, use the bit with rotary hammers that support SDS‑type shanks and have appropriate power for masonry drilling. Wear eye, ear and respiratory protection and use dust extraction or wet drilling methods where applicable to reduce airborne silica. Replace the bit when carbide wear or tip damage reduces drilling efficiency or hole accuracy.
