DEWALT DW5450 Rock 11/16-Inch by 8-Inch Carbide SDS Plus Hammer Bit
This DEWALT model uses a ROCK carbide tip for extended bit life and an elongated four-flute helix that facilitates faster material removal. The increased steel construction helps resist breakage in demanding conditions. Best for professional tradesmen who routinely drill into concrete and masonry, especially when long, reliable performance is required. Use this when you need a dependable bit for 11/16-inch holes in concrete walls or slabs.
Best for: professional electricians, plumbers, and HVAC installers who need a durable, reliable 11/16-inch bit for frequent use. Caution: remove dust regularly to maintain cutting efficiency; improper dust removal can reduce performance over time.
GRIXLEN 11/16 x 11 inch SDS Plus Masonry Drill Bit
This 11/16-inch bit features Alloy Steel with a carbide tip for longevity and robust performance in concrete, brick, and block. The 11-inch total length with an 8.5-inch working length balances reach and control for standard-depth drilling. Best for mid-range projects, such as installing wall anchors or piping runs in concrete walls. Choose this if you need a reliable all-around bit that fits SDS Plus tools.
Caution: depth stops or guides are recommended to avoid over-penetration in delicate substrates.
GRIXLEN 11/16 x 18 inch SDS Plus Masonry Drill Bit
This long 18-inch option is designed for deep drilling through concrete, brick, and block. The long overall length supports reach into thicker walls or deeper cavities while maintaining the same carbide-tipped performance. Best for specialist installations such as running long conduit or pipes through solid masonry. This is a better choice when standard-length bits do not reach the required depth.
Limitation: longer bits may be more prone to deflection in hard substrates; use a drill guide to maintain alignment.
GRIXLEN 11/16 x 10.2 inch SDS Plus Rotary Hammer Bit
This mid-length bit suits situations where you need depth without sacrificing control in tight spaces. The 10.2-inch length is a practical middle ground for many interior installations and masonry applications. Best for projects requiring a balanced blend of reach and maneuverability. Avoid this if you need extremely deep holes beyond 12 inches without multiple passes.
Tip: SDS Plus shanks require compatible hammer models; verify compatibility before purchase.
GUICGOC 11/16 x 12.2 inch SDS Plus Bit
This 12.2-inch long bit targets deeper masonry holes with an SDS Plus shank for secure tool engagement. Its 11/16-inch cutting diameter is well-suited for anchor holes and heavy-duty fastenings in concrete and stone. Best for professionals who need substantial reach without swapping bits mid-project. Caution: ensure the bit diameter clears any utilities or embedded elements before drilling.
GUICGOC 5 Pack 11/16 inch x 8.26 inch Bits
This five-pack provides a compact option for smaller jobs or as backup bits for multi-hole work. Each bit features a 11/16-inch cutting diameter and 8.26-inch length, with SDS Plus compatibility. Best for quantity needs and projects with repetitive drilling in concrete, brick, or cement. Caution: shorter length may limit depth in some installations; check hole requirements before use.
GRIXLEN 11/16 x 210mm (8-1/4 in) SDS Plus Bit
This shorter option is ideal for interior drilling with limited clearance. With 11/16-inch diameter and SDS Plus shank, it offers solid performance for medium-depth holes in concrete and masonry. Best for tight spaces and projects where a shorter, manageable bit improves control. Limitation: depth is capped at about 8-1/4 inches; plan holes accordingly.
Buying Guide: Key Considerations For 11/16 Inch Concrete Drill Bits
What is SDS Plus and why does it matter?
SDS Plus is a common shank standard that enables secure hammer action and quick bit changes on compatible rotary hammers. For 11/16-inch bits, ensuring your drill is SDS Plus compatible helps maximize bit life and drilling efficiency.
Carbide tip vs. plain steel
Carbide tips last longer and cut faster in masonry, especially through hard concrete or reinforced sections. Steel-only bits wear more quickly but may be adequate for light-duty projects or softer masonry.
Length and working depth
Longer bits reach deeper anchors or through thick walls. Shorter bits offer better control in tight spaces. Choose based on required hole depth and room to maneuver the drill.
Flute design and material removal
Multiple-flute designs increase chip evacuation, reducing clogging and heat. Four-flute designs in many SDS Plus bits balance cutting speed and control for concrete and brick.
Durability and use-case alignment
For frequent commercial use, invest in carbide-tipped bits with reinforced steel to minimize breakage. For occasional DIY tasks, a durable mid-length bit with solid build is often sufficient.
Practical tips for drilling masonry
- Drill with light, steady pressure to prevent bit binding.
- Keep the drill perpendicular to the surface for clean holes.
- Use a hammer drill in hammer mode for best results in concrete.
- Clear dust frequently to maintain cutting efficiency.
FAQ
- Q: What diameter is 11/16 inch in metric? A: Approximately 17.46 mm.
- Q: Can these bits be used with standard corded drills? A: They require an SDS Plus hammer drill or driver compatible with SDS Plus shanks.
- Q: Are carbide tips worth the extra cost? A: Yes for frequent or hard masonry tasks; they last longer and cut faster.
- Q: How deep can I drill with a 12.2 inch bit? A: Depth depends on drill length, bit length, and material; ensure your drill can accommodate the full length.
- Q: Should I use pilot holes with 11/16 inch bits? A: In hard masonry, pilots are not typically used; follow tool recommendations for best results.
- Q: How do I prevent breaking the bit? A: Avoid applying excessive force, maintain perpendicular alignment, and use proper pilot drilling when needed.
