Burrs matter more than they look. An external burr scrapes the sealing ring in a push-fit joint or drags cement out of a solvent joint, and an internal burr disturbs the flow and, in waste pipes, gives debris something to catch on. Cold weather changes the calculation with ratchet shears: PVC becomes noticeably more brittle below about 5 °C, and the shear can split the pipe rather than cut it, so a saw is the safer choice. ## The options, ranked *Ranked best-first for the stated job. The third column is why the others exist.* | Option | Good at | Bad at | | --- | --- | --- | | Rotary pipe cutter | Square, clean cuts every time with no swarf, and it works in tight spaces. | Leaves a raised internal burr that must be reamed out. | | Ratchet shear cutter | Instant one-handed cuts in small-diameter PVC, PEX and polyethylene. | Deforms the pipe end oval on larger sizes, and can crack PVC in cold weather. | | 24 TPI hacksaw | Cuts anything and is always to hand. | Hard to keep square by hand; a mitre box or a wrap of paper as a guide helps. | | Reciprocating saw with a fine blade | Fast in awkward positions such as under a floor. | Wanders badly, melts the plastic and leaves a poor edge for a solvent joint. | ## Technique that changes the outcome 1. Mark all the way round and cut square, using a mitre box or a taped guide 2. Deburr and chamfer the outside edge, and ream the inside 3. Wipe the cut end clean before priming or pushing into a fitting 4. Warm PVC pipe before shearing it in cold conditions, or use a saw instead ## What goes wrong - Leaving a burr inside a waste pipe - Ratchet shears on cold PVC - Cutting so short that the pipe cannot reach the stop in the fitting > Compiled practical guidance rather than a published standard. Product formulations vary by brand and market, so read the label — and where the work is structural, electrical or gas, the regulations that apply where you are govern rather than anything here. ## Other blade questions | For | Use | | --- | --- | | Metal | A bi-metal or carbide-tooth blade with at least three teeth in the cut — that tooth-count rule matters more than the machine. | | Tile | A continuous-rim diamond blade with water — and cut wet, because dry cutting tile produces respirable silica dust. | | Wood | 24 teeth for ripping and framing, 40 for general work, 60-80 for a clean crosscut finish. | | Plywood without tearout | A sharp 60-80 tooth blade, a scoring pass, tape on the line, and the good face oriented for the tool you are using. | | Brick | A segmented-rim diamond blade, cut wet or with on-tool extraction — brick and mortar dust is a serious silica hazard. | | Laminate | A triple-chip or negative-hook blade for worktops, and a reverse-tooth jigsaw blade for laminate flooring cut face up. | | Acrylic | A triple-chip negative-hook blade on a table saw, or score-and-snap for thin sheet — and keep the feed steady so it does not melt. | | Glass | None — a tungsten carbide scoring wheel, one firm pass with oil, then snap it. And toughened glass cannot be cut at all. | | Plasterboard | A utility knife for straight cuts and a jab saw or multi-tool for cutouts — a circular saw is the wrong tool entirely. | ## Common questions ### Which blade cuts plastic pipe?
