Blue Definition & Meaning - definition of bue

Short chipping materials, abrasive plastics, epoxy-based synthetic materials, fiberglass, copper, brass, bronze and router set-ups, or on a thin workpiece that may otherwise be pulled upwards.

A higher helix can also help with chip control by ejecting the chips at a steeper angle. Proper chip evacuation can help prevent chip packing or re-cutting of chips, especially in materials where we deliberately try to dissipate the heat on the chip itself. Higher helix angles are normally recommended, and perform well on gummy materials like aluminum, and excel in stainless and heat resistant alloys. However, the larger the helix, the less reinforced strength each cutting edge has. A disadvantage of a high helix is that due to its greater vertical force, it has been known to help pull the end mill out of collet fixturing (however most end mills pulling out of collet fixturing is due to user error or cutting parameters that are too aggressive, or the end mill not being tight enough in the collet).

When a cutting edge becomes dull, you just need to rotate the insert in the holder to use the sharp edge. When you buy the replacement inserts, be noted that the larger nose angles and larger tip radii enable a stronger cutting edge, but they result in increased vibration and a rougher finish.

Exceptions / non-returnable items Certain types of items cannot be returned, like custom products (such as special orders or personalized items), and personal care goods (such as beauty products). We also do not accept returns for hazardous materials, flammable liquids, or gases. Please get in touch if you have questions or concerns about your specific item. Unfortunately, we cannot accept returns on sale items.

Damages and issues Please inspect your order upon reception and contact us immediately if the item is defective, damaged or if you receive the wrong item so that we can evaluate the issue and make it right.

We believe the Right Tool Is Everything™, and we strive to share our experience and expertise in an effort to ensure you select the right tool for your application, every time. Download our Fundamentals Of End Mills Guide and learn the pros and cons of varying helix angles, coatings, tool materials and more, so you can confidently select the end mill that best meets your needs and suits your application.

Lower helix angles provide better edge strength, which is helpful in harder steels and cast irons. Tools with less than a 40° helix are typically more ideal for roughing applications due to their enhanced strength. Finishing quality, is however, compromised with these tool types, but can be overcome with a finishing cut, using a higher RPM and slower feed, where the tool removes a minimal amount of material. Therefore, low helix tools are better suited for applications requiring heavier cutting, when finish is not a priority.

Refunds We will notify you once we’ve received and inspected your return, and let you know if the refund was approved or not. If approved, you’ll be automatically refunded on your original payment method. Please remember it can take some time for your bank or credit card company to process and post the refund too.

Using a higher helix when not necessary can reduce tool life; and using too low a helix angle when unnecessary can create chattering and poor finishes. Therefore, a machinist must consider the helix angle of the cutting tool they use and how it can impact the efficiency of their application and the finish achieved.

Variable helix flutes also exist, where each flute will have a different helix angle, this is very helpful when high efficiency milling. The use of variable helix end mills can greatly reduce the chatter (noise & vibration), that is common in some applications.

Exchanges The fastest way to ensure you get what you want is to return the item you have, and once the return is accepted, make a separate purchase for the new item.

There are benefits to different helix angles as the various angles will produce different results. Higher helix angles can result in reduced tool pressure, better finishes, and less heat buildup. A 45° helix can increase the vertical force of a tool when compared to lower helix angles, which ultimately reduces load on the cutter. The gradual entry of the cutting edge increases the tool’s effectiveness, whether using advanced cutting tool programs in a machining center, or machining manually, as the higher helix angles can be fed at a higher rate.

There are many factors that impact the performance of the machining application. Often the helix angle is overlooked. The helix angle controls the angle of the cutting edge entering the workpiece as the tool rotates. The larger the helix angle, the more gradual the entry of the cutting flute. This creates a smoother transition as the cutting flute reaches the desired axial depth of cut.

The positive-rake feature enables the inserts to have an edge that is less than 90° to sit flat in the insert holder for improved cutting clearance and a better finish than negative-rake ones. The inserts have cutting edges on 1 side.

Variable helix end mills are the first choice for production or high-performance machining and for difficult to machine materials, such as stainless steels & heat resistant super alloys (HRSA).

We have a 30-day return policy, which means you have 30 days after receiving your item to request a return. To be eligible for a return, your item must be in the same condition that you received it, unworn or unused, with tags, and in its original packaging. You’ll also need the receipt or proof of purchase. To start a return, you can contact us at info@accusizetools.com. If your return is accepted, we’ll send you a return shipping label, as well as instructions on how and where to send your package. Items sent back to us without first requesting a return will not be accepted. You can always contact us for any return question at info@accusizetools.com.

Different manufacturers will utilize different angles (i.e. 37° vs. 38° for HRSA materials).* Utilize a higher helix angle for free machining stainless steels and materials with lower machinability rate (more difficult to machine) such as Inconel, titanium, A286, etc.
