Accusize Industrial Tools 5528-SX00 Premium M2 H.S.S. Chucking Reamer Set, Over & Under Size, 0.1240" thru 0.5010"
made from premium M2 high-speed steel. All chucking reamers are designed for accurate reaming in most materials using all types of equipment including screw machines, turret lathes, drill presses, and machining centers. They are regularly pointed with a 45°chamfer. The straight-flute design is recommended for most general-purpose reaming

As hole finishing tool, reamers are expected to help achieve desired tolerance that drill bits cannot do. Even though the intensity of the reaming process is mild, the required rigid setup and high volume of work are challenges that have to be confronted. To continuously provide steady quality surface during hole finishing, each single reamer from this premium reamer set was fully ground from single piece material, which makes each reamer less fragile than milled tools. Top M2 grade high speed steel further ensures fairly long using life.
Specifications
Reaming is normally performed under a low-speed manner and most of the time is conducted on existing holes so that bearing higher speed machining and shock resistance(high impact load) are normally not taken into consideration when making reamers. But meanwhile, neglecting high-speed performance also means giving up all advantages that high-performance H.S.S. attains.
M2 grade high-speed steel is the most widely used material in tool making for its superiorities. With higher wear resistance, anti-bending strength, toughness, and thermo-plasticity, M2 grade high-speed steel makes 5528-SF00 a better option for hole machining.
- High wear resistance: the reamers will less likely wear off during the machining process and have a longer cycle. Therefore, the quality of the work remains constant.
- Anti-bending strength and toughness: the reamers will only take a minor impact from each use. Both outside shape and inside the structure are not likely to change.
- Toughness: high toughness significantly shrinks machining duration, makes the work more efficient.
- Thermo-plasticity: although under a low cutting speed, the friction between the cutting tool and workpiece generates heat. Non-thermo-plasticity materials may subject to permanent hardness decrease. But M2 H.S.S. can effectively resist this type of harm and continuously serve as new tools.

I have nothing to say about the tools as I am returning the box unopened. I thought it is made in Canada but not, It is from China.Here is the reason: I use these tools to build sport aircrafts and ONLY use either US or German/Swiss made tools. I came to this decision after years of using dozens of tools from different manufacturers. My experience with made in China drill bits/reamers/taper taps is strictly negative. You never know what to expect. Very sad that US made drill bits and reamers are almost impossible to find.

First experience with Accusize and I am thoroughly impressed. The finish and packaging is very impressive. There packaging is better than Sterritt.

I have only used one reamer but they all appear to be well made, sharp and free from defects. The ones I checked were on spec. Case is very robust, excessive even. My regular reamers are envious.

I am careful to drill close to finished size before reaming and use plenty of cutting fluid. With these precautions they are working perfectly and show no signs of wear.

These reamers are fairly well made and will probably do an acceptable job. However, there is a double chamfer on each flute.The standard 45° chamfer on a reamer does most of the cutting, however, these reamers have a secondary chamfer behind the primary one. Precision reamed holes may be intermittent, depending on the hardness of the material being reamed.
