RUKO Step Drill 6.5–32.5 mm — HSS, Spiral-fluted, 9 Steps

RUKO Stufenbohrer Bohrber.6,5-32,5mm HSS Spiralnut Z.2 Stufen 9 is a step drill designed for preparing metric cable gland entries and rapid sheet-metal hole sizing

• HSS high-speed steel for long tool life
• Spiral-fluted for fast chip evacuation
• Cross-ground point for clean hole entry
• Shank with three flats for secure clamping

Faster process flow through fewer tool changes

The wide 6.5–32.5 mm step coverage in nine increments enables a single tool to produce a variety of hole diameters, which reduces machine downtime and the need for multiple drills. The combination of HSS material and a spiral-fluted geometry supports continuous drilling performance by aiding chip removal and lowering heat build-up; this translates directly into higher throughput and fewer interrupted production cycles. For panel fabrication and electrical enclosures, this means more holes per shift with fewer tool swaps.

Accurate entry and repeatable holes for cable glands

A cross-ground point with a 118° tip and a 90° step angle produces precise start points and defined step transitions, reducing burr formation and the need for secondary deburring. The two cutting edges provide stable cutting action while the shank with three flats ensures reliable clamping in chucks or collets, improving concentricity and repeatability. Such features make this step drill particularly suited to metric cable gland preparation and similar repetitive hole-making tasks where consistency matters.

Practical durability and simple handling for everyday workshop use

Constructed from HSS and featuring nine distinct steps, the tool balances longevity with versatility. The spiral flute not only assists chip evacuation but also helps maintain a cooler cutting zone, extending edge life under typical panel-working conditions. The stepped design removes the need for multiple size-specific drills, simplifying inventory and tool management. For any uncertainty about compatibility with specific panels or gland sizes, Metav Werkzeuge provides technical advice and data to support the selection process.

FAQ

What hole sizes does this step drill cover?
The RUKO step drill covers hole diameters from 6.5 to 32.5 mm in nine incremental steps (SKU 4000601759NW), allowing a single tool to produce multiple standard gland sizes.

Is the tool suitable for cable gland preparation?
Yes — it is specified for metric cable glands and is designed to produce the frequently required hole diameters cleanly and efficiently.

How is the drill secured in the machine?
The tool features a shank with three flats to ensure secure clamping in a chuck or collet, which improves concentricity and reduces slippage during drilling.

What cutting geometry does it use to ensure clean holes?
The drill has a cross-ground point with a 118° tip and a 90° step angle, which promotes precise hole entry and limits burr formation.

Does the tool have a coating?
No coating is indicated in the technical data; the tool is manufactured from HSS and relies on its material and flute geometry for performance.
