RUKO SPB-DIN345-29,5mm punta elicoidale HSS-E cono Morse MK3

For machinists and metalworking professionals drilling large holes in tough materials, the RUKO SPB-DIN345-29.5mm-HSS is a Morse taper shank twist drill bit engineered for precision and durability. Manufactured to DIN 345 standards from cobalt-alloyed high-speed steel (HSS-E), it delivers reliable performance in high-alloy steels, stainless steels, cast iron, heat-resistant steels, and titanium alloys up to 1200 N/mm² tensile strength.

Key specifications

• Diameter: 29.5 mm
• Overall length: 315 mm
• Flute length: 190 mm
• Shank type: Morse taper MK3
• Material: HSS-E (cobalt alloyed)
• Point angle: 130°
• Surface finish: bright
• Cutting direction: right-hand

Why choose it

Ground from solid for consistent accuracy, this drill bit features a standard core thickness and web taper for stable cutting. Its cobalt alloyed steel resists heat and wear, making it suitable for demanding industrial applications. The bright finish reduces friction and chip adhesion.

Ideal use cases

• Drilling large holes in high-alloy and stainless steels
• Machining cast iron and heat-resistant alloys
• Precision drilling in titanium components
• Use with Morse taper machines such as lathes and drill presses

Good to know

This drill bit does not have a coolant-through feature. It is designed for right-hand cutting only. For best results, use appropriate cutting fluid and secure the workpiece firmly.
