Drill bit AWTools SDS-plus Quadro Xtreme Black Line 8 x 210 mm

The AWTools SDS-plus Quadro Xtreme Black Line 8 x 210 mm drill bit is a masonry drill designed for use with hammer drills and rotary hammers fitted with SDS-plus chucks. With an 8 mm diameter and 210 mm overall length, this bit is intended for drilling into concrete, brick and natural stone. The Quadro tip geometry improves dust evacuation and helps maintain stable drilling performance during construction and renovation tasks.

Advantages

The Quadro Xtreme tip geometry promotes efficient crumb removal and reduces clogging while drilling in masonry materials. The SDS-plus shank enables quick, secure fitting in compatible hammer drills and rotary hammers, providing consistent energy transfer for effective impact drilling. The Black Line finish offers surface protection that can reduce wear from abrasive dust and extend useful life under normal working conditions.

Suitable for

• Drilling 8 mm diameter holes in concrete for anchors and dowels
• Making through-holes in brick for installation of electrical boxes and conduits
• Drilling into natural stone for fixtures and fastenings
• Construction and renovation tasks requiring repetitive masonry drilling with SDS-plus tools

When it may not be suitable

This drill bit is not intended for use in wood, metal, ceramic tiles or glass; using it in these materials will reduce performance and can damage the cutting edges. The 210 mm overall length limits reach compared with longer SDS-plus bits, so it may not be appropriate where deep or blind holes beyond this length are required.

Key specifications

• Shank type: SDS-plus
• Diameter: 8 mm
• Total length: 210 mm
• Tip geometry: Quadro Xtreme for improved dust removal
• Intended materials: concrete, brick, natural stone

How to use

Install the AWTools SDS-plus Quadro Xtreme bit into the SDS-plus chuck of a compatible hammer drill or rotary hammer until it locks securely. Select hammer mode for masonry drilling, align the bit with the marked drilling point, and apply steady pressure while allowing the tool to deliver impact force; avoid excessive sideways force. Withdraw the bit occasionally for deep or dusty holes to clear debris and reduce heat buildup. After use, clean the flutes and store the bit in a dry location to prevent corrosion.

What to consider before purchase

• Verify your drill accepts SDS-plus shanks.
• Confirm 8 mm diameter and 210 mm length meet hole size and depth requirements.
• Check that the work material is suitable (concrete, brick, stone).

Usage recommendations

Use in hammer mode on SDS-plus rotary hammers for best results; for repetitive drilling, allow the bit to cool periodically and clear debris to preserve cutting performance and extend service life.
