Best reciprocating saw blade for polycarbonate

A controlled cut setup for polycarbonate, with fit checks and the reasons behind each property.

High for blade class; verify product rating

Ground-tooth HCS or bi-metal blade for polycarbonate

Reciprocating saw can make this cut when machine fit, section thickness, tooth engagement, workholding, and dust or chip control are all verified.

Blade construction
Ground-tooth HCS or bi-metal blade
Teeth or grit
8–14 TPIConfirm the blade maker’s stated thickness range; tube wall thickness matters more than outside diameter.
Tooth geometry
Aggressive set with deep gullets
Machine fit
Standard reciprocating shank; blade length at least 115 mm for stroke clearanceThe blade must remain beyond the far face through the complete stroke.
Kerf / body
Blade body chosen for stiffness, curve radius, and access
Speed and feed
Steady feed that produces chips. Avoid pausing, rubbing, or forcing the work into the blade.

Set up the cut

  1. Clamp securely and avoid pausing in the cut.
  2. Steady feed that produces chips. Avoid pausing, rubbing, or forcing the work into the blade.
  3. The blade must remain beyond the far face through the complete stroke.
  4. Keep the shoe in firm contact and verify that the blade remains beyond the work through the full stroke.

Avoid

  • A dull fine-tooth blade that rubs and melts the kerf.
  • Unsupported offcuts that pinch, break away, or pull the tool off line.
  • A blade that is too short for the stroke or too wide for the required curve.
WHY THIS CLASS

The material and saw impose different constraints.

Polycarbonate is tougher than acrylic but still softens with heat and can grab if the tooth geometry is too aggressive.

Reciprocating saws trade finish for access and speed. Blade length, body thickness, tooth pitch, and construction determine control and survival.

The practical tradeoff

Confirm the blade maker’s stated thickness range; tube wall thickness matters more than outside diameter. The blade must remain beyond the far face through the complete stroke.
