Hand hacksaw STANLEY FATMAX 1-20-531 — manual metal and plastic cutting tool

STANLEY FATMAX 1-20-531 is a manual hand hacksaw engineered for cutting metal, plastic and other non-wood materials. The rigid die-cast aluminium frame offers strength with reduced weight, while the replaceable blade system and a supplied bi-metal blade (24 TPI) make it suitable for straight cuts, notches and flush cutting. The ergonomic bi-material soft grip and anti-skid surface provide control during use; an internal adjustable thumb-dial tension mechanism and spring-loaded device deliver high blade tension for stable, accurate cutting.

Advantages

The saw provides up to 150 kg of blade tension via an internal adjustable thumb dial and spring-loaded tension device, ensuring a taut blade for precise cuts. A die-cast aluminium body combines durability with light weight, and the bi-material soft grip with anti-skid texture improves handling during repetitive tasks. Blade positioning allows a 90° standard cut and a 45° flush cut, and the tool is supplied with a 24 TPI bi-metal blade for immediate use. A thumb grip feature supports accurate guiding of the blade along the cut line.

Suitable for

• Cutting steel and non-ferrous metal rods, pipes and profiles
• Trimming and resizing plastic tubing and fittings
• Workshop maintenance and on-site repair tasks
• DIY projects requiring straight cuts, notch work or occasional flush cuts
• Use in combination with standard hacksaw blades for different materials and finishes

Key specifications

• Frame material: die-cast aluminium for strength and reduced weight
• Blade type supplied: bi-metal blade, 24 TPI
• Blade tension: up to 150 kg (spring-loaded and thumb-dial adjustable)
• Cutting positions: 90° blade location and 45° flush cut capability
• Handle: bi-material soft grip with anti-slip surface and thumb grip for control
• Blade compatibility: standard hacksaw blades, replaceable

How to use

Fit a compatible hacksaw blade into the frame, ensuring teeth point away from the handle for a cutting stroke on the forward or backward motion as preferred. Use the internal thumb-dial to increase blade tension until the blade is taut; the spring-loaded mechanism assists in maintaining tension. Hold the bi-material grip firmly and align the thumb grip with the intended cut line. Start with light strokes to establish the cut, then use steady, even strokes to complete the cut while keeping the blade perpendicular for straight cuts or set the blade to the 45° position for flush trimming.

Usage recommendations

For best results, use the supplied 24 TPI bi-metal blade for general metal and plastic cutting; switch to a finer or coarser pitch blade depending on material thickness and finish requirements. Maintain even tension and replace blades when worn or damaged. Wear appropriate personal protective equipment and clamp workpieces securely to reduce vibration and improve cut accuracy.
