Product Spotlight: The Roscamat Mosquito — Compact Precision Tapping, Perfected
Share
In the world of precision tapping, compact doesn’t mean compromised. The Roscamat Mosquito proves that a small form factor, smart design, and rugged performance can coexist in one of the most versatile tapping arms on the market today.
Whether you're a small machine shop or part of a high-throughput assembly line, the Mosquito delivers controlled, repeatable thread tapping while reducing operator fatigue and boosting productivity.
Here's your full breakdown of the Mosquito—its capabilities, ideal applications, available configurations, and even its limitations—so you can decide if it’s the right solution for your tapping needs.
What Is the Roscamat Mosquito?
The Roscamat Mosquito is a compact articulated electric tapping arm designed for precision tapping up to 9/16" (M14) in materials like aluminum, brass, plastics, and mild steels. It’s the most lightweight and agile model in the Roscamat lineup, making it ideal for bench-level operations and tight workspaces. It’s also the most affordable electric arm in the Roscamat range, without sacrificing the brand’s hallmark industrial durability.
Ideal For:
- Tapping from #2–1/2" (M2–M14)
- Benchtop and light assembly applications
- High-repetition work in non-ferrous or soft metals
- Small component manufacturing, electronics, and light fabrication
- CNC shop integration for secondary tapping
- Industrial Production

Core Features of the Mosquito
✔ 360° Reach with Full Arm Articulation
Its three-arm joint design offers a full 360° work area, allowing operators to reach multiple tap points quickly without repositioning the workpiece.
✔ Torque Control Tap Adapters
Available with either rigid or torque control tap adapters, the Mosquito protects taps from breakage by clutching out under excessive strain. Torque control is highly recommended for most applications.
✔ Variable or Fixed Speed Electric Motor (300–600 RPM)
The Mosquito is available with either a variable speed electric motor (adjustable from 300–600 RPM) or a single-speed motor set at either 300 or 600 RPM. This allows you to select the motor type that best suits your material and tap size needs. The electric drive allows smooth operation and adaptability for a wide range of thread types and materials.
✔ Quick-Change Tap Holders
Swap out tooling fast with Roscamat’s standard quick-change holders, making it easy to adapt to various thread sizes and tap types.

Key Advantages of the Mosquito
✔ Compact Size, Big Capability
The Mosquito is perfect for limited bench space, tight workstations, or portable tapping setups. Despite its size, it can handle up to 9/16" (M14) threads with ease.
✔ Built for Industry — Heavy-Duty Quality
Don’t let the size fool you. The Mosquito is built with the same rugged, industrial-grade construction that Roscamat is known for worldwide.
✔ Boosted Operator Comfort
Reduce wrist strain, awkward angles, and repetitive motion injuries. The Mosquito provides smooth, balanced motion that lets operators work longer, more comfortably.
✔ Fast Payback for High-Volume Jobs
For shops with recurring tapping tasks, the labor savings and error reduction provided by the Mosquito quickly add up to a positive ROI.
✔ Perfect Companion for CNC Shops
Rather than occupying machine time, the Mosquito allows operators to tap holes on one part while the CNC machine works on the next. This parallel workflow increases throughput and operator efficiency.

What the Mosquito Does Best
Ideal Applications Include:
✔ Light manufacturing and assembly
✔ Electronics and enclosure production
✔ Machined aluminum parts
✔ Small or thin-walled components
✔ Secondary operations alongside CNC machines
Considerations & Limitations
While extremely capable, the Mosquito has its limits. Understanding those helps you pick the right model for your needs.
✖ Not Ideal For:
- Large workpieces requiring long vertical reach
- Tapping above 9/16" (M14)
- Tapping hardened steel or high-Rockwell alloys as a routine process
(though it can tap these materials occasionally) - Applications needing built-in depth control — for that, consider the Roscamat Shark or Tiger models
- Applications requiring tapping speeds below 300 or above 600 RPM
If you need a pneumatic version, the Roscamat 200 is the best alternative, offering similar design and function in air-powered form.
