At Radmore & Tucker we understand that a chainsaw is only as good as the bar and chain it runs on. That’s why our catalogue boasts an unrivalled range of guide bars and cutting chains, spanning lengths from a nimble 4‑inch pruner to a massive 48‑inch timber‑felling powerhouse. Whether you’re a weekend gardener tackling overgrown hedges or a professional arborist felling towering oaks, we have the exact match for your machine.

Our selection features industry‑leading manufacturers – Stihl, Husqvarna, Oregon, Makita and Echo – each renowned for durability, heat resistance and razor‑sharp performance. To make your choice effortless, every product page includes detailed specifications: bar length, pitch, gauge, tooth type and recommended saw models. Use our intuitive filter system to zero in on the perfect fit, then enjoy the confidence of a safe, efficient cut every time.

The Evolution of Chainsaw Teeth – From Scratcher to Super‑Chisel

Early chainsaws relied on bulky scratcher teeth, tightly spaced to limit bite depth but at the cost of speed. The game‑changing chipper chain, invented by Joseph Cox, introduced curled teeth with front‑mounted depth gauges, allowing each cutter to penetrate just enough wood for a swift cut without over‑loading the engine.

Modern chains have taken this concept further. Two dominant tooth profiles dominate today:

• Semi‑chisel (rounded) teeth: Found on many Oregon models, these retain sharpness when cutting hard, frozen or dirty timber. The rounded corners reduce the chance of dulling and make them forgiving on abrasive wood.
• Full‑chisel (square) teeth: Exemplified by Stihl’s Picco Super line, full chisel chains deliver blisteringly fast cuts in soft, clean lumber thanks to their razor‑edge geometry.

Choosing the right tooth type hinges on your typical workload. For occasional garden pruning or mixed‑wood projects, semi‑chisel offers longevity and versatility. If you spend most of your day felling fresh pine or processing logs for firewood, a full‑chisel chain will shave minutes off every cut.

Understanding Pitch, Gauge & Depth‑Gauge – The Trifecta of Fit

Pitch measures the distance between three consecutive rivets divided by two. It determines how tightly the chain sits on the bar and influences vibration levels. Common pitches in the UK market are 1/4″, 3/8″ (the most prevalent), .325″ and .404″. Selecting a pitch that matches your saw’s sprocket ensures smooth power transmission.

Gauge refers to the thickness of the drive links – essentially how wide the chain sits on the bar nose. The four standard gauges are 0.043″ (1.1 mm), 0.050″ (1.3 mm), 0.058″ (1.5 mm) and 0.063″ (1.6 mm). Pairing a chain with an incompatible gauge leads to premature wear, slipping or even dangerous bar‑breakage.

Depth‑gauge height (sometimes called the raker) controls how deep each tooth cuts into the wood. Too high and the chain will “skip” over the grain, slowing productivity; too low and you risk severe kick‑back. Our product pages list depth‑gauge specifications so you can fine‑tune performance for your specific task.

Bar Lengths – From Pocket Pruner to Heavy‑Duty Timber Bar

Our inventory covers the full spectrum:

• 4″–8″ bars: Ideal for cordless pruners, light landscaping and delicate branch work.
• 10″–18″ bars: The sweet spot for most residential users – perfect for fence clearing, firewood splitting and medium‑size tree removal.
• 20″–30″ bars: Favoured by professional arborists tackling larger trunks and commercial logging operations.
• 32″–48″ bars: Engineered for massive timber, large‑scale land management and industrial forestry.

Choosing a bar that matches the power output of your saw is crucial. Over‑loading a low‑horsepower machine with an excessively long bar can overheat the engine, while an undersized bar on a high‑output saw will waste its potential.

Safety First – Tips for Maintaining Peak Performance

1. Check tension daily: A correctly tensioned chain should sit snugly against the bar without sagging, yet move freely when pulled by hand.
2. Sharpen regularly: Use a file guide or professional sharpening service to maintain tooth angles. Dull teeth increase fuel consumption and raise kick‑back risk.
3. Monitor depth gauges: Replace or grind them back to the manufacturer’s spec after every 10–15 hours of heavy use.
4. Lubricate consistently: A well‑oiled chain reduces friction, prevents overheating and extends bar life.
5. Inspect for wear: Look for cracks in the bar nose, stretched links or missing teeth – replace components before they fail.
