October 21, 2026 Kyocera MagicDrill DRA Modular Drilling System
The Kyocera MagicDrill DRA is a high-efficiency modular drill manufactured by Kyocera. Designed to achieve high hole accuracy with low cutting forces, this drilling system incorporates advanced chisel edge geometry and optimized web thickness for demanding machining applications.
Key Features of Kyocera MagicDrill DRA
Engineered to overcome common hole-making challenges, the tool delivers exceptional stability and chip control across various drilling depths.
- Low Cutting Force Design: Features a special S-curve chisel edge that reduces thrust force by up to 35% and effectively suppresses chattering and vibration.
- High Rigidity Web Structure: Utilizes a 20% thicker web compared to conventional drills to minimize tool deflection and maintain roundness and cylindricity.
- Superior Chip Evacuation: Optimized chip thinning and support grooves with wider flutes on 5D and 8D holders enable smooth chip evacuation during deep hole cutting.
- Expanded Lineup: Available in 3D, 5D, and 8D holder lengths with large-diameter options ranging from ø26 mm to ø33 mm, including HQP high-precision steel machining inserts.
- User-Friendly Operation: Simplifies insert indexing and replacement directly on the machine without removing the toolholder.
Applications and Machining Performance
The DRA series is optimized for through-hole and deep-hole drilling in carbon steels, alloy steels, and stainless steel workpieces.
