38mm Core Drill HSS 30mm Cut Depth Weldon Shank 3/4" - Ruko GmbH

Take advantage of a robust combination of high-speed steel construction and a secure Weldon shank for reliable holemaking in steel and non-ferrous materials; the tool’s 30 mm cutting depth and ten cutting edges support efficient chip removal and consistent bore quality. Order the core drill directly via Metav Werkzeuge or request advice from the consultants if clarification of applications is required.

RUKO Core Drill Ø 38 mm — HSS, 30 mm cutting depth, Weldon shank

The RUKO Core Drill Ø 38 mm HSS is a precision metal-cutting tool intended for demanding through-hole and core-drilling work in steel, cast iron and light non-ferrous alloys.

• High-speed steel construction
• 30 mm cutting depth
• Weldon shank 19.05 mm (3/4")
• Suitable for steel, cast iron and non-ferrous metals

Consistent performance from high-speed steel for industrial use

The solid high-speed steel (HSS) body ensures sustained cutting performance and a good balance of toughness and wear resistance, which translates into fewer tool changes on medium-duty production runs. The combination of HSS and the drill’s ten cutting edges promotes even load distribution across the cutting zone, reducing the risk of chatter and producing cleaner bores. For workshop managers looking to keep cycle times predictable, this specification supports steady drilling rates while maintaining dimensional stability.

Accurate, secure clamping for repeatable holes

The Weldon shank (19.05 mm / 3/4") provides positive axial and torsional locking when used with a compatible Weldon-holder or chuck, which improves repeatability across batches. The relatively compact overall length contributes to reduced overhang, limiting deflection and supporting precision in tight-tolerance applications. Where fixture space is limited or where high concentricity is required, the shank design and solid HSS construction together help to keep the bore runout low.

Application range and material suitability explained

Designed for machining in steel (including structural profiles and large-format sheets), cast iron and a range of non-ferrous and light metals, the tool is suitable for workshops that require flexibility across common workpiece materials. The stated 30 mm cutting depth indicates the effective axial penetration for core removal; in practice this supports through-holes and partial-depth cores in medium-thickness components. For unfamiliar terms: a Weldon shank is a short flat on the shank that the set screw of the holder engages, while HSS denotes a tool steel optimised for elevated cutting temperatures.

Operational benefits and simple maintenance routine

Ten cutting edges and the HSS substrate together aid efficient chip formation and evacuation, reducing heat build-up during typical cycle times and extending usable tool life under recommended cutting conditions. Maintenance is straightforward: ensure secure clamping, inspect the cutting lips for wear, and clear chips regularly to preserve cutting geometry. For procurement and production planning, the single-piece packaging means immediate stock control is simple, and the durable construction reduces the frequency of replacements compared with lower-grade alternatives.

FAQ

What materials can this core drill machine?
The RUKO core drill (Ø 38 mm, HSS) is suitable for machining steel, cast iron and a variety of non-ferrous and light metal alloys in workshop and industrial settings.

Which toolholder fits the Weldon shank?
Use a Weldon-holder or chuck designed for a 19.05 mm (3/4") Weldon shank; the flat on the shank ensures secure clamping and torsional resistance for the RUKO core drill.

How deep can the drill cut effectively?
The tool provides a 30 mm cutting depth, which defines its effective axial penetration for core removal in typical component thicknesses.

How does the HSS material affect tool life?
HSS offers a balance of hardness and toughness at elevated cutting temperatures; for the RUKO core drill this means reliable wear resistance and stable cutting performance across medium-duty cycles.

Is the drill suitable for structural steel profiles and large-format sheets?
Yes, the specification explicitly cites suitability for steel such as T-profiles and large-format sheets, making it appropriate for structural and fabrication workshop tasks.
