Drill bit set Irwin SPEEDHAMMER PLUS IW2039501 — 9 pieces: 5×110, 5.5×110, 5.5×160, 6×110, 6×160 (2), 8×160, 10×160, 12×160

Set of 9 Irwin SPEEDHAMMER PLUS masonry drill bits in mixed diameters and lengths: 5×110, 5.5×110, 5.5×160, 6×110, 6×160 (two pieces), 8×160, 10×160 and 12×160. These SDS-plus shank-compatible bits are produced for rotary and hammer drilling in concrete, brick and other masonry materials, covering common hole sizes for anchor bolts, dowels and through-holes. The assortment gives tradespeople and DIY users a compact selection on site, reducing the need to stop work for bit changes and ensuring the right diameter and length are available for typical fixing tasks.

Advantages

The Irwin SPEEDHAMMER PLUS set offers hardened carbide tips and a flute geometry designed to evacuate masonry dust efficiently, which helps maintain drilling speed and bit life. The selection of diameters from 5 mm to 12 mm and mixed lengths up to 160 mm provides flexibility for shallow and deeper anchor or through-holes. Built for use with rotary and hammer modes, the bits balance durability and cutting performance for repeated drilling in concrete and brick.

Suitable for

• Drilling holes for anchor bolts and chemical anchors in concrete and stone
• Installing wall plugs and dowels in masonry and brickwork
• Through-holes for cable routing or pipe passages in renovation projects
• General construction and maintenance tasks requiring multiple bit sizes on site

Key specifications

• Set composition: nine bits in diameters 5 mm, 5.5 mm (two lengths), 6 mm (two pieces of different length), 8 mm, 10 mm and 12 mm
• Working lengths: 110 mm and 160 mm variants to match common fixing depths
• Shank type: SDS-plus compatible for use in hammer and rotary-hammer drills
• Tip material: carbide tip for masonry drilling
• Flute design: optimized for efficient dust removal during masonry drilling

How to use

Choose the bit diameter that matches the anchor, plug or conduit required for the application. Insert the SDS-plus shank into a compatible rotary-hammer drill and secure according to the drill manufacturer's instructions. For masonry drilling, start at low speed to position the bit, then use hammer function and moderate pressure to drill through concrete or brick. Withdraw the bit periodically to clear dust from the hole and maintain drilling performance. Match the bit length to the required hole depth to avoid excessive wear from over-penetration.

Usage recommendations

Use appropriate personal protective equipment (eye protection, dust mask and hearing protection) and clear the work area of loose debris. For accurate anchor performance, measure hole diameter and depth before fixing and clean holes of dust. Store bits in a dry case to protect carbide tips and prevent corrosion.
