Cylindrical drill bush DIN 179 form B, bore 17.5 mm, length 28 mm, outside dia 26 mm, ground

Where a hole of 17.5 mm has to sit in the same place on every part, this DIN 179 bush guides the tool. The medium length of 28 mm supports the drill, and the bore is rounded on both sides.

Benefits

• Guide length of about 1.6 drill diameters at 28 mm of length
• Overall length of 28 mm in the medium version of the range short, medium and long

Applications

• Hole patterns in assembly jigs and equipment frames
