SDS+ Drill Bit Irwin 14 x 240/300 mm for Hammer Drills — 14 mm Diameter, 240 mm Working Length, 300 mm Total Length

SDS+ Drill Bit Irwin 14 x 240/300 mm is a rotary hammer accessory designed for drilling into concrete, masonry and natural stone. The bit features a 14 mm cutting diameter, 240 mm effective working length and 300 mm total length, giving extra reach for deeper anchor or through-holes while staying compatible with SDS+ chucks. The geometry and flute design support stable centring and continuous removal of dust and debris during percussive drilling.

Advantages

The Irwin SDS+ 14 x 240/300 mm drill bit offers consistent drilling performance in hard substrates thanks to its optimized head geometry and flute profile that evacuate rubble efficiently. Its extended working length allows access to recessed or deep mounting points without the need for extensions. The SDS+ shank system ensures secure, wobble-free coupling with hammer drills that accept SDS+ bits, reducing bit slip and improving drilling accuracy.

Suitable for

• Drilling anchor holes in concrete for mechanical fixings
• Creating through-holes in masonry and brickwork
• Installing rebar dowels or long fasteners in structural elements
• Professional and DIY tasks requiring deeper reach into hard substrates

Key specifications

• Cutting diameter: 14 mm
• Working length (usable drilling depth): 240 mm
• Total length: 300 mm
• Shank type: SDS+ compatible
• Suitable materials: concrete, masonry, natural stone

How to use

Install the SDS+ shank firmly into the hammer drill’s chuck until it locks. Select an appropriate drill speed and hammer function according to the drill manufacturer’s guidelines and the hardness of the material. Start drilling with moderate axial pressure, allowing the percussive action to remove material; withdraw periodically to clear accumulated debris for cleaner holes and to avoid overheating. When drilling to depth, use a depth stop or mark the bit to ensure consistent hole depth. After drilling, remove dust from the hole before inserting anchors or fasteners.

Usage recommendations

For best results, use the Irwin SDS+ 14 x 240/300 mm bit in hammer drills rated for SDS+ accessories and matched to the bit diameter. Wear appropriate personal protective equipment including eye and hearing protection and a dust mask when drilling in concrete or masonry. Replace the bit when wear reduces cutting performance or causes excessive wandering.
