Klein Tools 31430 High Tension Hacksaw – 30,000 PSI, Converts to Jab Saw, Dual Bi-Metal Blades

Overview

The Klein Tools 31430 High Tension Hacksaw combines rugged durability with practical versatility, built for professionals and serious DIYers who tackle metal, PVC, and wood. The reinforced frame stays steady under tension, helping you guide the blade with confidence. This tool feels balanced in the hand and ready for demanding jobs, from framing to conduit work.

Tool-Free Jab Saw Conversion

Switching from hacksaw to jab saw is completely tool-free thanks to a simple reciprocating blade mount. On a busy worksite, this seamless conversion reduces downtime and keeps your workflow moving as you tackle different materials and tight spaces.

Performance and Versatility

At the heart of its performance is an adjustable tension system that supports up to 30,000 PSI, keeping the blade taut for crisper, more accurate cuts. The design also accommodates both 45-degree and 90-degree blade mounting, giving you flexibility for long face cuts or corner work.

• Heavy duty frame provides stability for long cuts and tougher materials
• Bi-metal blades resist wear for longer life between changes
• In-frame storage keeps spares accessible and protected

What’s Included and How It Helps

The kit ships with two blades to cover common jobsite needs: a 12-inch blade at 24 TPI for general cutting and a 6-inch blade at 24 TPI for tight spaces and reciprocating tasks. The two-blade setup reduces the need to carry extra tools or swap parts mid-project.

• 12-inch blade handles longer, straighter cuts with smooth progress
• 6-inch blade runs in tight quarters and near edges
• Bi-metal construction boosts blade longevity under frequent use
