What to know before buying
Listing details to confirm
The listing is inconsistent about the cutting angle: one field gives "6E+1 Degrees", while the item highlight and product description claim 90°. It also gives 12mm as the cutting diameter despite listing 16mm and 19mm sizes. Confirm the intended angles and how the diameters relate to the three sizes before purchase.

This gives a broadly favourable but not unanimous snapshot. Ratings alone do not establish why buyers responded as they did or confirm the claimed bit sizes and materials.
