The Dormer A296-225 is a professional 5-piece HSS centre drill set designed for creating precise centre holes in shafts to enable secure holding during machining operations. Manufactured to DIN 333A standard, this bright-finished tool set is suitable for use in both CNC and conventional machines, making it ideal for engineering workshops, metalworking facilities, and professional machinists. Constructed from high-speed steel (HSS), these centre drills prevent work piece material from sticking to the cutting edge, ensuring clean, accurate holes. The set is versatile enough to drill through a wide range of materials including steels, aluminium, and stainless steel, providing reliable performance across diverse machining applications. The A296-225 set includes five British Standard sizes (BS1, BS2, BS3, BS4, and BS5), covering the most commonly required diameters for shaft preparation and centring work. Manufactured in France by Dormer, a respected name in precision cutting tools, this compact set delivers professional results for both production environments and precision engineering tasks.
