RUKO guide pin D6.35 mm — 55 mm cutting depth, HSS / Weldon shank

The RUKO guide pin D6.35 mm for accurate alignment with HSS core drills, offering a 102 mm overall length and secure Weldon-shank fastening

• For HSS core drills
• Weldon shank fastening
• 55 mm effective cutting depth
• 102 mm overall length

Precise alignment for consistent core-drilling results

A reliable pilot or guide pin ensures that each core drill starts true and remains concentric throughout the cut. Made for compatibility with HSS core drills, the component reduces lateral movement during penetration, lowering the risk of wandering and ensuing rework. The documented 55 mm cutting depth and compact overall length deliver controlled engagement, while the robust Weldon shank interface provides repeatable mechanical location. For workshops that prioritise production uptime, this alignment aid translates into fewer rejected parts and steadier cycle times.

Secure clamping reduces runout and improves surface finish

Secure fastening is central to machining accuracy. The Weldon shank connection secures the pin to the arbor or toolholder with positive locking, which minimises rotational runout and improves the finish of the drilled bore. Combined with the high-speed steel compatibility, this arrangement supports stable cutting conditions, helping to prolong the life of both core cutters and the guide pin itself. The result is a measurable reduction in vibration and an increase in first-pass acceptability for batch and single-piece production alike.

Simple integration into existing tooling and maintenance routines

Designed to work directly with standard core-drilling setups, the guide pin requires no complex adapters: it accepts conventional Weldon-style clamping and fits common arbor configurations. The 102 mm overall length gives sufficient engagement for handling and extraction, while the form factor enables straightforward replacement during routine maintenance. Clear labelling and standardised interface reduce downtime during changeovers and make stocking spare parts easier, supporting lean workshop logistics and predictable throughput.

FAQ

What core drills is this guide pin compatible with?
The guide pin is designed for use with HSS core drills and secures via a Weldon shank, ensuring compatibility with standard HSS core tooling assemblies (SKU 4000602781NW).

How does the Weldon shank improve performance?
The Weldon shank provides a positive mechanical lock that reduces runout and vibration, which improves bore quality and extends cutter life when using the RUKO guide pin.

What are the key dimensions to check before ordering?
Confirm the overall length of 102 mm and the specified 55 mm cutting depth to ensure the guide pin meets the physical requirements of the arbor and the drilling application.

Is the guide pin suitable for heavy-duty production environments?
Yes; its secure Weldon fastening and compatibility with HSS core drills make the guide pin appropriate for repetitive industrial drilling where consistent alignment is required.
