Stubby Drills DIN 1897 RN
DIN 1897 stubby twist drills in RN execution are designed for drilling holes in metal workpieces. Their short design provides greater rigidity than longer drills of the same diameter, supporting stable performance in shallow drilling applications.
Applications:
Used for drilling through holes and blind holes in metal components. Suitable for operations where compact tool dimensions, rigidity and controlled feed are important. Suitability for a particular workpiece material depends on the drill material, coating and manufacturer’s recommendations.
Operating Principle:
As the drill rotates, its cutting edges remove material while the spiral flutes carry chips away from the cutting zone. The actual hole diameter and surface quality depend on tool runout, clamping accuracy, cutting edge condition and operating parameters.
Diameter and Length:
The drill diameter determines the nominal hole size. Overall length and flute length vary with the selected size. The stubby design reduces tool overhang but limits access to recessed surfaces and the available drilling depth.
Cutting Section:
The spiral flutes provide space for chip evacuation. Monitor chip accumulation during drilling, particularly when machining materials that produce long chips. Flute length does not equal the maximum drilling depth: sufficient clearance must remain for chips to exit the hole.
Tool Geometry:
DIN 1897 specifies the dimensional series for stubby twist drills. RN identifies the tool execution. Specific geometry angles, cutting material and coating should be checked in the specifications of the selected drill.
Practical Recommendations:
Secure the workpiece and clamp the drill with the minimum overhang required for the operation. Feed the tool along its axis without applying lateral force. Use coolant or lubricant appropriate for the workpiece material and clear chips regularly.
Specifications:
- Tool type: twist drill for metal
- Series: stubby
- Standard: DIN 1897
- Execution: RN
- Diameter: depends on the selected size
- Overall length: depends on the selected size
- Flute length: depends on the selected size
Cutting Characteristics:
The short design reduces the drill’s tendency to bend. Accurate positioning, low runout and a steady feed help achieve consistent hole quality.
Cutting Parameters:
Select spindle speed and feed according to drill diameter, workpiece material, drill material, hole depth and cooling conditions.
Suitable Operations:
- Drilling through holes and blind holes
- Machining components with an accessible drilling area
- Drilling with minimal tool overhang
- Operations requiring increased drill rigidity
Limitations:
The stubby series provides limited drilling depth and reach. These drills are not intended for side milling, enlarging holes through lateral pressure or drilling with the tool misaligned.
