Needle scalers are versatile tools, used for countless applications, and they’re essential across many industries.
That’s why selecting the right needle scaler for the job is important. Having the appropriate tool can speed up your jobs, ensure better safety and improve efficiency, so you can achieve the results you need without unnecessary strain or downtime.
In this guide, we will take you through the different types of needle scalers, what they’re best suited for and what all the technical terms really mean, so you can have confidence in your choice.
Selecting the right handle type
The handle type can make a big difference to comfort and control, depending on your application and working position.
B models and the VL233 model feature an in-line handle which offers a straight grip that’s ideal for precision and control in tight spaces.
BPG models along with the VL203 and VL303 models come with a pistol grip and provides a more ergonomic hold, especially for extended use or heavy-duty applications.
Understanding needle scaler models
Needle scalers come in a range of sizes and configurations to suit different tasks. The Trelawny B series needle scalers come in three sizes, simply numbered 1 to 3, with either a B or BPG designation. The VL range is available in two sizes and offers a choice between in-line and pistol grip variants. Here’s a quick breakdown of each model based on needle count and application:
1B Compact and light, the 1B model features 12 needles, ideal for light applications or working in tight or hard-to-access areas.
2B / BPG and VL203 / 223 These models come with 19 needles and are widely considered to be the industry standard. They strike the balance between weight and performance, making them suitable for general-purpose use.
3BPG and VL303 Our largest models are equipped with 28 needles, built for maximum performance and high productivity. They are only available with a pistol grip and are best suited for demanding surface preparation jobs.
All our needle scalers are fitted with 3mm diameter needles as standard, suitable for a wide range of surface preparation tasks.
Key terminology
Understanding the key terms will help you get the most out of your product. Here are the main terms and what they mean:
Blows per minute and impact – Our larger needle scaler models have a longer stroke and a larger piston, providing greater impact force. If you’re removing hard scale and coatings, then the additional power is critical to fracture the material. For lighter surface removal tasks, a higher blow frequency can be more effective as it provides finer impact without excessive force.
Low vibration – The VL range delivers powerful and reliable performance. Our Vibro-Lo anti-vibration technology offers up to eight times lower vibration emissions for enhanced operator comfort.
Non-sparking or ATEX rated – For added protection in hazardous environments, look for the “H” symbol – this means the scaler can be fitted with non-sparking needles. For full ATEX-rated safety, our VL ex models are the ideal choice, built with the same low-vibration technology as our trusted VL range.
Needle and chisel attachments – All models are available as a needle or chisel variant, depending on your needs. You can also purchase a combination kit that includes both attachments. If you already own a needle scaler, needle and chisel attachments can be bought separately as retrofit options, so you can upgrade your tool without replacing it.
Air consumption – Measured in cubic feet per minute (CFM) or litres per minute (LPM), air consumption is critical to any tool’s performance. Choose your model based on your compressor’s output and the number of tools you plan to use at the same time.
Dust control – When removing coatings and rust, it’s important to protect the operator and the surrounding environment from hazardous dust. Tools marked with the TVS logo are fitted with the Trelawny Vacuum System. This system can be purchased with integrated shrouds or as optional accessories and used with HEPA-rated dust collectors for safer working conditions and reduced clean-up time.
