Drill bit GRAPHITE SDS+ 14 mm for concrete, model 57H460

The GRAPHITE SDS+ 14 mm drill bit (model 57H460) is designed for drilling precise 14 mm diameter holes in concrete and other masonry materials. Compatible with SDS+ rotary hammer chucks, this drill bit is intended for applications that require reliable concrete penetration and stable hole dimensions for anchors, dowels and through-fixing. The cutting geometry and tip profile are optimized for impact drilling in solid materials while maintaining concentricity during rotation.

Advantages

The SDS+ shank ensures secure retention in compatible rotary hammers and enables fast bit changes. A durable carbide tip and hardened flute construction extend service life under repeated impact loading. The 14 mm diameter provides a standard size for many fastening systems, offering consistent hole sizing for anchors and bolts. The bit’s balance between toughness and rigidity reduces the risk of bending or breakage during typical concrete drilling tasks.

Suitable for

• Drilling 14 mm holes in concrete for anchor bolts and expansion anchors
• Creating through-holes in masonry and blockwork
• Professional construction and renovation tasks requiring repeatable hole sizes
• DIY projects where reliable concrete drilling is needed using an SDS+ rotary hammer

Key specifications

• Shank type: SDS+ compatible
• Drill diameter: 14 mm
• Intended material: concrete and masonry
• Tip: carbide-tipped cutting head for impact drilling
• Use: rotary hammer in hammer mode with rotary function

How to use

Fit the SDS+ shank securely into the rotary hammer chuck, ensuring the bit locks in place before starting the tool. Select hammer or rotary-hammer mode appropriate for concrete drilling, apply steady axial pressure and allow the tool’s impacts to do the cutting—avoid excessive lateral force. Withdraw the bit periodically to clear dust from the hole and improve drilling efficiency. For deep holes, use intermittent drilling and cleaning to maintain bit performance and reduce heat buildup.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection and work gloves. Match drill diameter to anchor or dowel specifications and check the rotary hammer speed and impact settings recommended by the power tool manufacturer. For reinforced concrete, proceed cautiously and consider using a dedicated rebar-cutting accessory if necessary.
