Bosch EXPERT Power Change Plus Pilot Drill - 7.15 x 105mm

Its primary function is to accurately center hole saws and guide them into the material, ensuring a clean start and preventing the hole saw from wandering.

HSS-G stands for High-Speed Steel Ground. This indicates the material is high-speed steel that has been ground to shape, known for its hardness and ability to withstand high temperatures during drilling, making it durable and long-lasting.

No, this pilot drill is specifically designed for the Bosch EXPERT Power Change Plus system and compatible Bosch EXPERT hole saws with a 60mm cutting depth. It will not fit other systems.

You attach it by simply pushing it into the Bosch EXPERT Power Change Plus keyless interface on the arbor until it clicks securely into place.

The working length of this pilot drill is 60mm, which is designed to extend through the material being drilled to guide the hole saw effectively.

While made of HSS-G, its primary use is to guide hole saws. For specific metal drilling applications with hole saws, ensure the hole saw itself is rated for metal and use appropriate cutting fluid and speeds.

Ensure you are using a Bosch EXPERT Power Change Plus arbor and that the pilot drill is aligned correctly with the interface before pushing it in until it clicks.

The pilot drill tip is made of HSS-G and is designed for long life, but if it becomes noticeably dull or bent, it should be replaced to ensure optimal performance and safety.

Verify that the pilot drill is securely clicked into the arbor and that the arbor itself is properly mounted and tightened in your drill chuck. Ensure the hole saw is correctly seated on the arbor.
