I would say that it's good for the tool wear because the built up edge it's like a coating which protect the tool. Possibly move the tool wear.
But it's bad for the skin of the piece (poor surface finish), and you don't have dimentional control (temporarily change the global shape of the tool), you over heat the piece and work hardening.
To summarize, try to avoid it (increase speed and lubricant).

Affecting factor of tool life in machinability?
The life of tool is affected by many factors such as: cutting speed, depth of cut, chip thickness, tool geometry, material or the cutting fluid and rigidity of machine. Physical and chemical properties of work material influence tool life by affecting form stability and rate of wear of tools. The nose radius tends to affect tool life.1. Cutting speed: Cutting speed has the greatest influence on tool life. As the cutting speed increases the temperature also rises. The heat is more concentrated on the tool than on the work and the hardness of the tool metrix changes so the relative increase in the hardness of the work accelerates the abrasive action. The criterion of the wear is dependent on the cutting speed because the predominant wear may be wear for flank or crater if cutting speed is increased.2. Feed and depth of cut: The tool life is influenced by the feed rate also. With a fine feed the area of chip passing over the tool face is greater than that of coarse feed for a given volume of swarf removal, but to offset this chip will be greater hence the resultant pressure will nullify the advantage.3. Tool Geometry: The tool life is also affected by tool geometry. A tool with large rake angle becomes weak as a large rake reduces the tool cross-section and the amount of metal to absorb the heat.4. Tool material: Physical and chemical properties of work material influence tool life by affecting form stability and rate of wear of tool.5. Cutting fluid: It reduces the coefficient of friction at the chip tool interface and increases tool life.
What are the advantages and disadvantages of knife edge?
disadvantage: concentrated stress on tip results in increased wear, in turn the follower becomes less accurate over time
How do you compare tool steel grades?
Tool steels are compared to each other. They are usually measured by toughness, hardness and wear resistance. The toughness is detemined by an Charpy impact test. The hardness is measured by a Rockwell hardness tester and reported as HRC or RC. The wear resistance is measured by a number of tests that measured the amount of material removed from the original size after a repetitive movement against an abrasive material. These figures are then gathered and presented on a chart. The grades are then compared with one another based on these three properties. See the links below for more information on comparing tool steels.
Is welding slag harmful?
When it is molten or hot it can burn. After it cools there doesn't seem to be any harmful effects from coming into contact with it. It is very hard so when chipping it be sure to wear eye protection.
Is there a tool that can grind or file cement?
Of course there is! It's a diamond wheel that fits on an angle grinder, or in a special concrete grinding machine. Be sure to wear all your PPE--face mask, hearing protection, eye protection.
What is meant by 'flank wear' in regards to cutting tools?
Tool wear resulting in the gradual wearing away of the cutting edge. Flank wear is mostly caused by abrasion, is predictable, and is the most desired form of tool wear.
What is the best bike chain wear tool to accurately measure the wear of my bike chain?
The best bike chain wear tool to accurately measure the wear of your bike chain is a chain checker tool. This tool is designed to quickly and easily determine the level of wear on your chain, helping you know when it needs to be replaced to prevent damage to your bike's drivetrain.
What is shoulder tread wear a sign of?
Wear on both edges is a sign of under inflation. Even wear on one edge is a sign of camber out of spec. Uneven wear on one edge is a sign of toe out of spec.
What is the motto of Mechanix Wear?
The motto of Mechanix Wear is 'The Tool That Fits Like a Glove!'.
What is feathering of tires?
Feathering is a uneven edge wear that can make the edge of the tire look like a saw blade.
What safety precautions should be taken when using a sharp cutting tool?
When using a sharp cutting tool, it is important to always keep the blade pointed away from yourself and others. Use the tool on a stable surface and make sure to keep your fingers away from the cutting edge. Always cut away from your body and wear protective gloves if necessary. Additionally, make sure to keep the tool clean and sharp to prevent accidents.
Why tool wear is imp in metal cutting?

Will incorrect tire inflation cause tire wear?
Yes. Low pressure will cause edge wear. Over inflation will cause center wear.
Does this have a subject and verb Most of the effects of caffeine quickly wears off?
Yes. The subject is "most" and the verb is "wear" -- "most" uses the singular verb "wear" and not wears.Most of the effects of caffeine quickly wear off. = Most wear (off).
What do Germans wear every day or on special holidays?
Germans wear what people in the United States do with more of a European edge.
Why bevelling is done?
Beveling is done to proved an smooth tapered edge. This will be done to an edge for the sake of safety or to decrease the amount of wear on the surface.
Why align the tire?
So it will run true and not wear out one side or edge.
