Dewalt DT8923-QZ DT8923-QZ-Broca XLR SDS+ 8x160x100

DeWalt DT8923-QZ XLR SDS+ Drill Bit – 8 mm × 160 mm × 100 mm

The DeWalt DT8923‑QZ is a premium SDS+ XLR drill bit engineered for high‑performance drilling in concrete, masonry, natural stone and reinforced concrete. Its compact dimensions – an 8 mm diameter, 160 mm length and 100 mm cutting depth – make it ideal for precision work where space is limited yet power and durability are essential.

Key Features

• Full‑Head Carbide Construction: The entire head of the bit is forged from high‑grade carbide, providing exceptional hardness and resistance to wear. This design ensures a longer service life even under aggressive drilling conditions.
• XLR Technology: The XLR (Extreme Light) system incorporates a lightweight yet robust core that reduces vibration and improves drill stability. It also allows for faster penetration rates compared to standard SDS+ bits.
• SDS+ Shank: The 8 mm shank fits securely into any SDS+ hammer drill or rotary hammer, delivering maximum torque transfer and minimizing slippage during drilling.
• Optimized Cutting Geometry: Four precisely engineered cutting edges are arranged to maximize chip evacuation while maintaining a sharp profile. This geometry reduces heat buildup and extends the bit’s usable life.
• Versatile Application Range: Suitable for drilling through reinforced concrete, unreinforced masonry, natural stone, and even high‑strength artificial stone. Its robust design handles the toughest materials without compromising performance.

Performance Highlights

The DT8923‑QZ delivers high drilling speeds thanks to its lightweight core and efficient cutting edges. Users report a significant reduction in drill vibration, which translates into smoother operation and less operator fatigue. The bit’s carbide head resists chipping even when encountering embedded steel reinforcement, making it reliable for structural applications.

Installation & Usage Tips

• Proper Alignment: Before drilling, ensure the bit is fully seated in the SDS+ chuck. A loose fit can lead to premature wear or breakage.
• Use Appropriate Speed Settings: While the XLR system tolerates higher speeds, starting at a moderate RPM (around 300–400 rpm for rotary hammers) helps maintain control and reduces heat.
• Apply Light Pressure: Let the drill do the work. Excessive force can cause overheating or bit failure.
• Regular Cleaning: After each use, clean the cutting edges with a brush to remove debris that could impede chip evacuation.

Maintenance & Longevity

The carbide construction of the DT8923‑QZ means it can withstand repeated drilling cycles without significant degradation. However, for optimal longevity:

• Inspect the bit periodically for signs of edge wear or chipping.
• Replace immediately if any cutting edges become dull or damaged.
• Avoid using the bit on materials that exceed its rated capacity (e.g., extremely hard granite) to prevent premature failure.
