Wire Gauge Drills - Short Length (891431120)
The Wire Gauge Drills - Short Length 891431120 are engineered for professionals who demand exact wire sizing and flawless drilling performance. Crafted from premium high‑speed steel (HSS) and optimized for short‑length applications, these drills deliver the precision you need for copper, aluminum, and multi‑strand wiring projects.
Key Benefits & Features
- Precision‑Engineered Geometry: Optimized flute and point angles provide clean, burr‑free holes for accurate wire gauge measurements.
- Short Length Design: Compact 25 mm shank reduces tool protrusion, ideal for tight spaces and CNC spindle compatibility.
- Durable High‑Speed Steel (HSS) Construction: Offers excellent wear resistance and maintains sharpness even after extended use.
- Universal Compatibility: Fits standard 3/8‑in. and 1/2‑in. collet chucks, making it perfect for manual drills, bench drills, and automated CNC stations.
- Corrosion‑Resistant Coating: TiN (Titanium Nitride) coating extends tool life and reduces heat buildup during high‑speed drilling.
- Easy Identification: Laser‑etched size markings on the shank allow quick selection and inventory management.

Why Choose the 891431120 Short Length Wire Gauge Drill?
When precision is non‑negotiable, the 891431120 short length drill stands out. Its compact design minimizes deflection, ensuring accurate hole placement even in the most confined environments. The TiN coating reduces friction, extending tool life while delivering consistent performance across a wide range of materials.
Ideal Use Cases
- Installing conduit and wiring in cramped panels or tight enclosures.
- Manufacturing of custom cable assemblies where exact wire gauge matching is critical.
- Repair and maintenance of automotive and aerospace electrical systems.
- Prototyping and low‑volume production runs requiring rapid tool changes.
Installation & Maintenance Tips
- Secure the drill in a 3/8‑in. or 1/2‑in. collet chuck, ensuring the shank is fully seated.
- Use cutting fluid or air cooling for extended drilling sessions to prevent overheating.
- Inspect the TiN coating regularly for wear; replace the drill when coating degradation is evident.
- Store drills in a dry, dust‑free container to preserve sharpness and prevent corrosion.
