Q

To cut angle iron and heavy pipe with a hand hacksaw, you should use a blade with what number of teeth per inch?

🔍 Key Concepts

• Relationship between material thickness and appropriate teeth per inch (TPI) on a hacksaw blade • Difference between cutting thin‑wall vs thick/heavy sections • How too many vs too few teeth per inch affect cutting speed and blade life

💭 Think About

• Which TPI is normally used for thick, solid stock like heavy pipe or angle, as opposed to thin sheet metal? • What happens if you use a very fine-tooth blade (high TPI) on thick, heavy material—does it clear chips well, or does it tend to clog and cut slowly? • What happens if you use a very coarse blade (low TPI) on heavy sections—does it bite well enough without breaking teeth?

✅ Before You Answer

• Remember the typical TPI ranges: coarse (around 14 TPI), medium (around 18–24 TPI), fine (around 32 TPI) • Match the TPI to heavy, solid sections, not thin tubing or sheet metal • Eliminate the TPI that would be more appropriate for very thin material where you need many teeth in contact to avoid snagging.
