I use this bur to start many procedures including crown measurement cuts,
I have had a very high percentage break off at the neck in a routine usage.
One break occurred when prepping a lateral incisor access for a root canal.
I returned the bag for credit but I didn't feel the product was good quality.

Good Product but they are single use for tooth structure only. Sometimes break while getting into old amalgams.

packaging not good

Bur #557 easily fractures under minimal pressure, leading to a challenging situation where I struggled to retrieve the broken tip from inside the patient's mouth before the risk of ingestion. This experience has caused considerable stress, and I am dissatisfied with the product. Not recommending

They work well. Fast shipping.

good quality

i know it 's house brand, but it's not sharp at all and once use it gets dull quickly.

I am the first one who tells you:" Be realistic", " you get what you pay for" So my expectation was very low and I consider burs as single use. But the quality would not allowed to finish 2-3 fillings at once. Literary you start using new bur and already feel that it is not cutting properly. As a result I decided not to use them as there is risk of overhitting. By the way, they don't even stick to magnetic bur holder. That say a lot of quality of steel used.

mediocre

I wish I could sent a picture... I used 6 burs on one patient on a virgin tooth with decay... Not only do the snap at the neck but they are dangerous as they go flying... I've ordered before and a few break but this pack is beyond ridiculous!!!

ok for one use

better quality now, no more break like before

good product for routine filling preps. predictably break when cutting off PFM crowns

Really one use, but work well

Breaks easily.

Burs are garbage and dull. Does not cut well and ended up throwing them away. Waste of money

They dont cut great because they are not very sharp

Very dull with my electric handpieces.

Net32 Response: In an attempt to provide a better result, seeing as house brands can vary from vendor to vendor, Net32 sent a house brand product from another vendor at no charge to the customer. A $68.00 value.

Sold by First Dent Supply. Came in unmarked package. Wish I could return them.

This is the downside of buying from Net32: you don't have a direct relationship with the supplier, and they can send you whatever crap they want.

I don't have time to return...Midwest Type? That's BS...why not state the manufacturer? It would have saved me the time and money...Not happy at all


Net32 Response: The description of the product has been changed from Midwest Type to House Brand. House brand indicates that various manufacturers' products may be sent in fulfillment.

Though MIDWEST burs was the title in larger font the remaing description stated Midwest type so when received they were house brand not Midwest.

great price but dulls and breaks easily

does not cut .will break at slight resistance or old amalgame..do not waste your cash.

Net32 Response: Net32 sent the customer a pack of Beavers Dental FG #557 burs for the customer to try at no charge to the customer. An $85.00 value.

These burs made in Poland are terrible. Very dull and does not cut well, several have fractured during tx. I have purchased "Midwest type" burs from net32 before and they used to be pretty good.

Net32 Response: Net32 sent the customer a pack of Beavers Dental FG #557 burs for the customer to try at no charge to the customer. An $85.00 value. LV Dental has been delisted for this product due to multiple negative complaints.

Good price for a decent bur.

Perhaps it me but some seem to cut better than others from same batch.

Good cross cutting bur for removing ceramic and good for class 2 preps

pretty durable

This bur is ok but not as good as the Midwest we normally get

Good product.

Will buy more

Do not cut as well as name brand

Don't cut well through metal

Cuts well and price was reasonably less than other vendors

Good burs good price

This have the individual plastic cover on each bur. Much more sharp then the ones that don't. Beware of the bulk pack without the individual plastic covers. Update: LV no longer sells 557 with plastic ocvers. House brand is very dull and waste of $$$.

was of good quality so far -- have not had many issues breaking

not bad.Very fast delivery .

one time use only and even then sometimes the bur head detaches while using and is a choke hazard. Also, rusts as soon as autoclaved if want to reuse.

Works well

Good quality

Not sure if these burs are defective, but they are only good for one or two procedures. After that, they are breaking!
