Review: Works but very poorly - Works but very poor due to very cheap fabrication. Plenty of runout, especially the pilots. Couldn't get them to not make the part wobble like crazy and had to change the set screws as the ones it comes with are so short, you can very easily strip the 2 or 3 thread engagement if not very careful and then they would likely loosen. Review: Quality control issues - counterbores have no flutes - I received this set and no flutes were cut on the counterbores. They are just circular blanks. This is the second defective item from Accusize in two weeks. ## Features - 14pcs pilots: 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10, & 10.5mm - 6pcs counterbores: 8.5, 9.5, 10.5, 11.5, 13.5, & 16.5mm - 1pc 10mm straight shank holder - Supplied in a premium fitted case. - Straight shank ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BRDJ79GC | | Brand | Accusize Industrial Tools | | Brand Name | Accusize Industrial Tools | | Customer Reviews | 4.2 out of 5 stars 9 Reviews | | Finish Types | Uncoated | | Finish type | Uncoated | | Item Dimensions | 25 x 9 x 6 centimeters | | Item dimensions L x W x H | 25 x 9 x 6 centimeters | | Manufacturer | Accusize Co., Ltd. | | Material | High Speed Steel (HSS) | | Material Type | High Speed Steel (HSS) | | Model | 3620-0122 | | Number of Packs | 1 | | Number of Pieces | 21 | | Part Number | 3620-0122 | | Set Name | Accusize Industrial Tools 21 Piece Metric H.S.S.
