Product Information

Full details

The Bosch Professional U 127 D jigsaw blade is designed for professional metalworkers and fabricators who require rapid, straight-line cuts in aluminum and non-ferrous metals. Its primary strength lies in its specialized tooth geometry which maximizes speed and material removal, though users should note it is strictly optimized for metal and will not perform well on wood or abrasive materials.

FAQs

Can I use this blade on steel?

This blade is specifically engineered for aluminum and non-ferrous metals; it is not recommended for hardened steel.

Does this fit T-shank jigsaws?

No, this blade is designed exclusively for jigsaws with a U-shank connection.

What is the maximum aluminum profile diameter it can cut?

The blade is rated for aluminum profiles and pipes up to 30 mm in diameter.

Is coolant necessary?

While not strictly required for thin sheets, using a cutting lubricant or coolant can extend the life of the blade and improve finish quality.

Can I make curved cuts with this blade?

The U 127 D is optimized for straight, fast cuts; it is not recommended for tight-radius curves.

Troubleshooting

Blade wandering or drifting

Ensure the jigsaw shoe is securely tightened and held firmly against the material surface during the cut.

Blade binding during cut

Check that the feed rate is not too high; allow the blade to clear chips through the gullets without forcing it.

Excessive vibration

Verify that the blade is properly seated in the U-shank chuck and the material is clamped down tightly.

Pros and Cons

Pros

  • High-speed cutting performance in aluminum
  • Durable fully hardened HSS material
  • Efficient chip removal due to large gullets
  • Universal fit for U-shank jigsaw models

Cons

  • Not suitable for wood or abrasive materials
  • Requires specific thickness ranges for best results
  • Limited to straight cuts

Setup, Compatibility & Care

To install, ensure your jigsaw is unplugged or the battery is removed. Insert the U-shank into the blade holder until it clicks into place. Before starting, verify that the shoe of your jigsaw is flush against the material to minimize vibration. Compatibility is guaranteed with any jigsaw model equipped with a standard U-shank receiver. For care, keep the blade clean of metal filings after use. If the cut quality begins to degrade, it is likely due to tooth wear, and the blade should be replaced to prevent heat buildup in the workpiece.
