Drill Bit Smart SDS Plus Quattro 12x310/250 — Smart

Smart SDS Plus Quattro 12x310/250 is a carbide-tipped SDS Plus drill bit designed for rotary hammers. With a nominal diameter of 12 mm and an overall length of 310 mm (working length 250 mm), this drill bit is intended for drilling into concrete, masonry and similar mineral substrates. The SDS Plus shank ensures secure retention in compatible hammer drills and enables efficient impact energy transfer for deep hole drilling.

Advantages

The Quattro geometry and carbide tip deliver improved drilling speed and wear resistance compared with conventional plain-shank bits. The SDS Plus connection provides positive locking and easy bit changes without additional tools. Extended working length allows reaching deeper anchoring points and through-holes while maintaining stability during hammering. The bit construction balances drilling performance and tool life for both professional and DIY tasks.

Suitable for

• Drilling holes in concrete and reinforced concrete for anchors and dowels
• Making passage holes through masonry and brick
• Installing electrical boxes, plumbing sleeves and fastening systems
• Construction and renovation tasks requiring deeper boreholes

Key specifications

• Nominal diameter: 12 mm
• Overall length: 310 mm
• Working length: 250 mm
• Shank type: SDS Plus
• Tip material: carbide
• Intended materials: concrete, masonry, brick and similar mineral substrates

How to use

Fit the SDS Plus shank into the hammer drill’s chuck until it locks. Select the hammer mode on the drill and position the bit on the marked drilling point. Apply steady axial pressure while allowing the hammer action to perform the cutting; avoid excessive lateral forces that can bend the bit. Clear dust from the hole periodically by withdrawing the bit or using a blow-out pump to maintain drilling efficiency. For reinforced concrete, start with moderate feed pressure and increase as the hole progresses.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask. Match drill speed and hammer settings to the material and bit size; higher impact settings suit hard concrete, while lower speeds help when approaching reinforcement. Replace the bit when the carbide tip is worn or when drilling performance noticeably decreases.
