The five-cutter set is made for machining injector seats in common rail engines and removes leaks between the injector and the seat. The cutters have a hardness of 58-60 HRC and come with a pilot pin and T-knob in a storage case from Beast.

The set covers cutter sizes from 15 to 17 mm and several body diameters, so that different injector mounts in Fiat, Iveco, Bosch, Mercedes-Benz, Delphi, BMW, PSA, Renault and Ford engines can be machined.

What makes injector seat cutters BST-350007 a strong choice for common rail engines?

The set cures leakage in the injector seat, which causes loss of compression and increased oil consumption. The cutters are made from CrMoV SKD11 and hardened to 58-60 HRC. The pilot pin keeps the cutter centred in the seat during machining.

The cutters in the set are:

• Angle cutter 17 mm with 21 mm body diameter for Fiat and Iveco
• Flat cutter 17 mm with 19 mm body diameter for Bosch and Mercedes-Benz CDR
• Flat cutter 17 mm with 17 mm body diameter for Delphi, Bosch, BMW, PSA, Renault and Ford
• Stepped flat cutter 15/17 mm with 19 mm body diameter as a universal cutter
• Angle cutter 17 mm with 17 mm body diameter for Mercedes-Benz CDI

How injector seat cutters BST-350007 are used in the engine workshop

The cutter is chosen according to the seat shape and body diameter of the injector, guided by the pilot pin and turned by hand with the T-knob. The set also includes a spindle and a hex key, and everything fits in the supplied case.

Frequently Asked Questions (FAQ)

Do the BST-350007 cutters fit injector seats in every engine?

No. The cutters are made for common rail injector seats with cutter diameters of 15, 17 or 17/15 mm and body diameters of 17, 19 or 21 mm. Seats with other dimensions cannot be machined with the set.

How are leaks removed with the BST-350007 cutters?

Yes, the set is made for that. The cutter is guided by the pilot pin in the injector seat and turned with the T-knob, which exposes a clean sealing surface. The cutters have a hardness of 58-60 HRC and are made from CrMoV SKD11.

What sets the BST-350007 cutters apart from other injector seat cutters?

The set has five cutters of different shapes: two angle cutters, two flat cutters and one stepped 15/17 mm universal cutter. It also includes a pilot pin, T-knob, spindle and hex key in one case.
