DeWalt DT1957-QZ, Disc Circular Saw 250 * 30mm * 48T

The DeWalt DT1957-QZ is a circular saw blade designed for fast cutting with extended durability in construction applications and general-purpose woodworking tasks using portable circular saws. Here’s a breakdown of its key features:

Specifications:

• Diameter: 250 mm (9.84 inches)
  • This is a large diameter blade, allowing for deep cuts in wood.
• Arbor: 30 mm (common arbor sizes are 16mm and 20mm, so this is a less standard size)
  • Ensure your circular saw has a 30mm arbor to ensure proper fit. Check your saw’s manual or markings on the arbor itself.
• Number of Teeth (TPI): 48
  • This is a medium-high tooth count, offering a balance between:
    • Cutting Speed: Still allows for reasonably fast cutting.
    • Finish: Provides a decent cut quality for construction work and many general-purpose applications.

Features:

• C2 Construction Grade Carbide: These teeth are impact-resistant and can handle potential encounters with nails or debris embedded in wood, making them suitable for construction projects.
• Ultra-Sharp Carbide Edges: Contribute to clean cuts and reduced splintering in wood.
• Alternate Top Bevel (ATB) Tooth Geometry: Similar to other DeWalt blades mentioned, the teeth are angled slightly outwards for a smoother cutting experience with less drag on the wood.
• Nail Tough Design: Specifically designed to handle cutting through nail-embedded wood with minimal damage to the blade.
• Ribbed Heat Vents: Allow the blade to run cooler, reducing blade flexing and binding during cuts.
• Anti-Stick Coating : Minimizes friction and gumming on the blade for smoother cuts and prevents the blade from binding in the wood (not all sources confirm this feature).

Applications:

• Construction lumber cutting:
  • Framing
  • Rough carpentry
  • Ripping and crosscutting lumber (dimensional lumber)
• General-purpose woodworking tasks where a balance between speed, decent cut quality, and nail resistance is desired

Benefits:

• Fast Cutting with Durability: The combination of a larger diameter, medium-high tooth count, and C2 carbide construction allows for efficient cutting while handling potential nail encounters.
• Clean Cuts with Reduced Splintering: Sharp edges and ATB tooth geometry contribute to a good quality cut for general purposes.
• Nail Tough: Designed to resist damage from embedded nails.
• Cooler Blade Operation: Ribbed heat vents help maintain performance.
• Reduced Friction (on some models): Anti-stick coating (if present) helps prevent binding.

Overall, the DeWalt DT1957-QZ is a robust circular saw blade for construction projects and general woodworking that prioritizes fast cutting, durability against nails, and a decent cut quality. The larger diameter, C2 carbide teeth, and nail-tough design make it suitable for demanding tasks.
