Reciprocating saw blade DeWALT DT20774-QZ Bimetal 3.2 cm

The DeWALT DT20774-QZ bimetal reciprocating saw blade is engineered for cutting a variety of materials including metal, plasterboard, plastics and timber with embedded nails. With a short working length of 3.2 cm, the blade provides a compact cutting profile suitable for confined spaces and controlled demolition or trimming tasks. Constructed from bimetal for improved toughness, the blade balances flexibility and edge retention for repeated use in mixed-material applications.

Advantages

This bimetal reciprocating saw blade offers enhanced durability compared with high-carbon alternatives, reducing the risk of tooth breakage during aggressive cuts. The short 3.2 cm working length enables precise plunge cuts and access in tight areas while maintaining stability in the holder. The tooth design is optimized to cut through both ferrous materials and softer substrates, allowing a single blade to be used across multiple tasks and reducing the need for frequent blade changes.

Suitable for

• Cutting metal profiles and pipes in renovation or repair work
• Removing sections of plasterboard or drywall
• Cutting plastic components and composite panels
• Trimming timber that contains nails or fasteners
• Controlled plunge cuts and work in confined spaces

Key specifications

• Blade material: bimetal construction for improved toughness
• Working length: 3.2 cm for compact cutting operations
• Compatible use: designed for reciprocating saws with standard blade mounts
• Cutting capability: suitable for metal, plasterboard, plastic and wood with nails
• Design features: reinforced tooth geometry for mixed-material performance

How to use

Install the blade in the reciprocating saw according to the tool manufacturer's instructions, ensuring secure locking in the blade holder. Select an appropriate cutting speed and apply steady pressure; allow the blade to do the work rather than forcing it, particularly when transitioning between materials such as wood and metal. For plunge cuts, position the tip at the start point and use controlled strokes to avoid excessive bending. Replace the blade if teeth become visibly worn or if cutting performance decreases.

Usage recommendations

Use suitable personal protective equipment including eye and hearing protection and gloves. When cutting metal or materials that may generate sparks or dust, ensure adequate ventilation and clear the work area of flammable materials. For best life and performance, match feed rate and speed to the material being cut and avoid overheating the blade.
