Baileigh TN-250 Tube Notcher
The Baileigh TN-250 is a professional grade hole saw tube notcher designed for precision tube and pipe notching applications. With its patented self centering radial vise system and robust American made construction, this tool delivers accurate, repeatable notches on tubing from 16mm to 64mm OD, even in the most challenging positions including bent sections.
When you need to notch tubing in tight spots or awkward angles, the TN-250 changes everything. Unlike conventional V-block notchers that struggle with bent tubes or off center positioning, this innovative tool features a revolutionary 6-jaw radial vise that grips your workpiece anywhere, anytime. Whether you're working on the middle of a bend, need an offset notch, or require precise angular cuts up to 220 degrees, the TN-250 handles it all with confidence.
Built in the United States from heavy duty 19mm steel plate, this notcher is engineered for professional fabricators, custom chassis builders, and serious DIY enthusiasts who demand precision and reliability. The massive 32mm Thompson shaft rides on sealed, oiled needle bearings for smooth, vibration free operation that extends the life of your hole saws while delivering cleaner cuts. Every component interlocks to create an incredibly rigid platform that won't flex or move during operation, giving you the accuracy you need for perfect tube joints every time.
What sets the TN-250 apart is its versatility. You can mount it to your workbench, clamp it in a vise, or even attach it directly to installed tubing for on chassis work. The large engraved degree dial makes angle setup quick and precise, while the adjustable mounting rails let you offset notches up to 25mm vertically. This is the notcher that adapts to your workflow, not the other way around.

Key Features & Benefits
- Patented Self-Centering Radial Vise: This is the only hole saw notcher that automatically centers itself on any size tube, eliminating setup time and ensuring perfect alignment every single time. The 6-jaw system grips tubing anywhere, even in the middle of bends where conventional notchers simply can't reach.
- 220-Degree Pivot Range: Access the "back side" of notches effortlessly. When tubes intersect at complex angles or you're working in tight spaces, the carriage pivots far enough to approach from either direction, giving you flexibility other notchers can't match.
- Adjustable Offset Capability: Need your notch slightly off-center? The dual slotted mounting rails allow vertical offset adjustments up to 25mm (1 inch), perfect for creating saddle joints and asymmetrical connections without complex setup procedures.
- Heavy-Duty American Construction: Built from 19mm thick steel plate with all interlocking components, this notcher won't flex, vibrate, or compromise your cuts. At 23kg, it's engineered to last decades in professional shop environments.
- Premium Thompson Shaft with Sealed Bearings: The 32mm shaft runs on sealed, oiled needle bearings for buttery-smooth rotation. Unlike cheaper notchers, both ends of the shaft are completely replaceable, saving you money on maintenance and extending the tool's working life.
- Wide Capacity Range: Handle tubing from 16mm to 64mm (5/8" to 2.5") OD in a single tool. Compatible with standard bi-metal hole saws and accommodates deeper 76mm (3-inch) hole saws for longer cuts in a single pass.
- Large Engraved Degree Scale: No squinting or guessing. The clearly marked degree dial helps you set up complex angles quickly and accurately, essential for creating perfectly mating joints on the first try.
- Lifetime Technical Support: Baileigh backs the TN-250 with a 1-year parts warranty plus lifetime phone support from experienced fabrication specialists. When you have questions or need troubleshooting advice, help is just a call away.

Frequently Asked Questions
Can the TN250 really notch tubing that's already bent?
Yes! This is one of the TN-250's standout features. The self-centering radial vise can clamp onto tubes in virtually any position, including directly in the middle of a bend. This capability is unique to the TN-250 and eliminates the need for complex workarounds when notching pre-bent tubing for roll cages and chassis work.
What size drill do I need, and does it have to be corded?
You'll need a standard 1/2" (12.7mm) chuck drill. While you can use a cordless drill, a corded drill is strongly recommended for consistent power and torque, especially when cutting through thicker-walled tubing or making deep notches. The continuous power prevents stalling and delivers cleaner, faster cuts.
How long does assembly take, and is it complicated?
Assembly typically takes 5-10 minutes and requires only basic hand tools. You'll attach the radial vise handle, mount the degree dial, and install the shaft and bearing assembly to the main body. The included hardware and straightforward design make it a simple process, even if you're not mechanically inclined.
Can I use this for stainless steel and aluminum tubing?
Absolutely. The TN-250 works beautifully with mild steel, stainless steel, aluminum, chromoly, and other tube materials. Just make sure you're using the appropriate hole saw for your material (bi-metal saws for steel, carbide-tipped for stainless) and proper cutting lubricant for best results and extended tool life.
Is the TN250 suitable for professional shop use or just hobbyist projects?
The TN-250 is built for professional fabrication shops and sees heavy use in chassis building, off-road fabrication, and custom metal shops. Its heavy-duty construction, replaceable components, and consistent accuracy make it ideal for daily commercial use. That said, serious hobbyists and DIY fabricators will also appreciate its capabilities and durability for weekend projects and custom builds.
What's the smallest tube I can reliably notch with this tool?
While the specifications list 16mm (5/8") as the minimum, many users report that practical minimum is closer to 32mm (1.25") for the most secure clamping. For smaller diameter tubing, you may need to fabricate custom adapters or consider the smaller TN-210H model from Baileigh's lineup.
