Drill SDS+ Irwin 8 x 50/110 mm

Irwin SDS+ drill bit 8 x 50/110 mm is designed for use with rotary hammers that accept SDS+ shanks. The bit has an 8 mm diameter, a 50 mm working length and a total length of 110 mm, making it suitable for drilling through concrete, masonry and natural stone. Its SDS+ shank ensures secure retention in compatible chucks and reliable power transfer during impact drilling operations.

Advantages

The drill bit delivers consistent penetration into hard substrates thanks to its precisely ground tip and robust flute geometry. Compatibility with SDS+ rotary hammers provides quick tool changes and reliable holding. The 50 mm working length balances reach and stiffness for common installation tasks, while the 110 mm overall length allows drilling through moderate thicknesses and for through-hole applications. The bit’s construction is intended for repeated use in professional and DIY applications where concrete and masonry drilling is required.

Suitable for

• Drilling holes in concrete for anchors and fasteners
• Creating through-holes in masonry and block walls
• Installation of electrical boxes, conduit and plumbing fixtures
• Repair and renovation work involving stone or brick substrates

Key specifications

• Diameter: 8 mm
• Working length (usable length): 50 mm
• Total length: 110 mm
• Shank type: SDS+ compatible
• Intended materials: concrete, masonry, natural stone

How to use

Fit the SDS+ shank securely into the rotary hammer’s chuck until it locks. Select hammer or hammer-drill mode according to the tool’s settings and apply steady axial pressure while allowing the tool to perform the cutting and percussion action. Start drilling at low speed to establish the hole position, then increase force as required. Periodically withdraw the bit to clear debris from the hole and cool the cutting edges. Use appropriate personal protective equipment including eye and hearing protection.

Usage recommendations

For best results when drilling concrete or dense masonry, use a rotary hammer with SDS+ system and choose an appropriate feed rate; excessive side pressure should be avoided to prevent premature wear. For anchor installation, ensure hole depth and diameter match the anchor manufacturer’s instructions. Replace the bit when wear noticeably reduces drilling efficiency.
