RUKO VOB-3S-30 Weldon Shank HSS-Co Core Drill 10.0 mm Cutting Diameter, 30 mm Cutting Depth

For machinists and metal fabricators using magnetic drilling machines, the RUKO VOB-3S-30 core drill delivers precise holes in steel, stainless steel, cast iron, and non-ferrous metals. Its 10.0 mm cutting diameter and 30 mm cutting depth make it suitable for a range of drilling tasks in structural steelwork and fabrication shops.

Key specifications

• Tool type: Core drill (annular cutter)
• Material: HSS-Co (high-speed steel with cobalt)
• Cutting diameter: 10.0 mm
• Cutting depth: 30 mm
• Shank type: Weldon shank, 19 mm (3/4 inch)
• Number of cutting edges: 3
• Overall length: 64 mm
• Coolant supply: Internal
• Manufacturing process: Fully ground

Why choose it

The fully ground HSS-Co construction with three cutting edges provides efficient chip evacuation and stable cutting performance. The Weldon shank ensures secure clamping in magnetic drilling machines, while internal coolant supply helps dissipate heat for longer tool life.

Ideal use cases

• Drilling holes in steel plates and beams
• Creating holes for bolts, rivets, or wiring in metal structures
• On-site fabrication and maintenance with magnetic drills

Good to know

An ejection pin is required for slug removal. The drill is uncoated and suitable for materials with tensile strength up to 1100 N/mm².
