Drill Bit DeWALT DT9582-QZ 1.6 cm 450 mm Rotary Hammer

The DeWALT DT9582-QZ 1.6 cm x 450 mm rotary hammer drill bit is engineered for professional and demanding drilling tasks. Designed to work with rotary hammers, this long SDS-plus-compatible bit offers a 1.6 cm diameter and a 450 mm length to reach deeper holes while maintaining consistent performance. The construction and geometry of the cutting tip are intended to provide efficient material removal and prolonged service life when used in concrete and masonry.

Advantages

This DeWALT rotary hammer drill bit combines robust materials with precise tip geometry to deliver reliable drilling performance. The extended 450 mm length allows access to recessed or deep anchor points without the need for extensions, and the bit's diameter provides a balance between hole size and structural stability. The bit is designed for compatibility with common rotary hammer chucks and to withstand repeated impact loads typical of heavy-duty drilling.

Suitable for

• Drilling through concrete and reinforced concrete
• Creating holes in brick and masonry for anchors and bolts
• Installing long anchors, sleeves and through-fixings
• Deep drilling where standard-length bits are insufficient

Key specifications

• Type: Rotary hammer drill bit suitable for hammer drilling
• Diameter: 1.6 cm
• Length: 450 mm overall length
• Shank interface: SDS-plus compatible shank for rotary hammers
• Tip design: carbide-tipped or reinforced cutting geometry for masonry and concrete (manufacturer design)
• Material: hardened steel body with wear-resistant cutting tip

How to use

Select a compatible rotary hammer with an SDS-plus chuck and secure the bit in the tool according to the manufacturer's instructions. Mark the drilling position and, if necessary, use a center punch or starter mark to prevent walking. Begin drilling at low speed to establish the hole, then apply consistent pressure while allowing the hammer action to perform the cutting. Withdraw the bit periodically to clear dust from deep holes and to avoid overheating. Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask when drilling.

Usage recommendations

For best results, match drill speed and applied pressure to the base material: lower speeds and steady pressure for reinforced concrete, moderate speeds for brick and masonry. Inspect the bit before use for signs of wear or damage and replace when cutting performance declines. Use dust extraction or vacuum attachment where possible to reduce concrete dust exposure.
