05F113 - Walter 13mm Carbide Tipped Annular Cutter - 30mm Depth

Technical Overview of the Walter Carbide Core Cut 13mm

The Walter 05F113 is a high-performance 13mm annular cutter from the renowned Carbide Core Cut series, engineered specifically to address the challenges of machining hard and abrasive materials. Unlike standard High-Speed Steel (HSS) cutters, this tool utilizes premium tungsten carbide tips brazed onto a specialized alloy body. This construction allows the cutter to maintain hardness at elevated temperatures, a critical factor when drilling materials with low thermal conductivity such as stainless steel and high-tensile alloys. The 30mm depth of cut provides sufficient reach for drilling through thick plate and structural members commonly found in heavy industrial applications.

The geometry of the 05F113 is a result of extensive research and development by Walter Surface Technologies. The flute design has been optimized to maximize chip evacuation efficiency. In deep hole drilling, chip packing is a primary cause of tool failure and poor surface finish. The Carbide Core Cut's aggressive flute profile ensures that swarf is ejected rapidly, reducing heat buildup and friction at the cutting interface. This design feature, combined with the inherent hardness of the carbide inserts, enables operators to run magnetic drilling units at higher RPMs and feed rates compared to traditional tooling, significantly reducing cycle times.

Precision is paramount in the design of this cutter. The 13mm diameter is held to tight tolerances to ensure hole accuracy, which is essential for bolted connections and structural integrity. The cutter is designed to minimize vibration and chatter, which not only improves the surface finish of the hole—often eliminating the need for reaming—but also extends the life of the magnetic drill motor and gearbox. For maintenance, repair, and operations (MRO) professionals dealing with cast iron, uneven surfaces, or composite materials, the shock resistance of the carbide tips offers a reliable solution that resists chipping and breakage under load.

Furthermore, the shank design ensures compatibility with a broad range of magnetic drilling machines, making it a versatile addition to any industrial tool crib. Whether utilized in a controlled workshop environment or on-site for field repairs, the Walter 05F113 delivers consistent, measurable performance improvements over conventional drilling methods.
