SDS Plus to M16 Threaded Core Drill Bit Adapter D16-20

Connecting M16 threaded core drill bits to SDS Plus rotary hammers can be a frustrating challenge, often requiring expensive proprietary adapters or compromising on stability. The AH14161 Driving Device with SDS Tip D16-20 solves this by providing a robust, industrial-grade bridge that lets you use standard M16 core bits with your existing SDS Plus hammer drill, saving money and expanding your tool's versatility.

Who is it for

Professional contractors, electricians, plumbers, and serious DIYers who need to drill large-diameter holes in masonry, concrete, brick, or stone using core bits. If you already own an SDS Plus rotary hammer and want to avoid buying a dedicated core drill, this adapter is the perfect solution.

Main features

• Precision-machined SDS Plus shank ensures a secure, wobble-free fit in any SDS Plus chuck.
• M16 external thread on the accessory side accepts all standard M16 core drill bits (16–20 mm diameter range).
• High-grade steel construction with industrial durability for demanding jobsite conditions.
• Quick-change mechanism allows fast bit swaps without tools.
• Compact 100 mm overall length maintains optimal reach and control.
• Silver/grey finish resists corrosion and wear.

Tips

Always apply a small amount of grease to the M16 threads before attaching a core bit to prevent seizing. Use the hammer drill's rotation-only mode (if available) for core drilling to reduce stress on the adapter and bit. For deeper holes, periodically withdraw the bit to clear debris and prevent overheating.
