Drill sharpeners are available in multiple types. Out of these types, structural differences and the features that they offer can greatly affect the outcome of the sharpening process. These types include drill bit grinding attachment, manual drill bit sharpener, electric drill bit sharpener, and bench-mounted drill bit sharpener.
These are usually added to angle grinders to create a sharpening tool. People like these attachments because they are versatile and can be easily fitted to equipment that most people already own. Sharpening drills also offer control when sharpening is desired. However, achieving a consistent angle might be difficult without practice.
This sharpener is an easy-to-use handheld device that can be used to sharpen drill bits. There are grooves in the V-shaped slots that correspond to the various angles of the drill bit. The user inserts the bit and then pulls it through to sharpen it. It is cheaper and lightweight. Therefore, it is a practical option for small DIY-oriented users.
Although interesting and amusing, this is somewhat less effective than electric sharpeners when dealing with larger bits or industrial workloads.
These are powered devices designed for the precise sharpening of drill bits. They are fitted with rotating grinding wheels and the user funnels the bit into a designated slot. The machine then pulls the bit through, automatically sharpening it to the correct angle. Due to their ease of use and efficacy, these are commonplace in professional settings.
These sharpeners are affixed to a workbench or in a workshop, often featuring multiple grinding wheels for various bit sizes. The process usually involves manually positioning the bit for precise sharpening. These are durable and maintain a high level of precision, even with heavy use, unlike handheld sharpeners.
These are particularly useful for businesses or individuals with large drill bit investments.
There are huge variance in the drill sharpeners applications. Thus, understanding these applications can help a buyer make a more informed decision when purchasing drill sharpeners. The article considers the following applications: metalworking industry, woodworking industry, construction industry, and mechanical industry.
In the metalworking industry, precision is everything. The drill bits used in machining and fabrication processes must be incredibly sharp to ensure clean cuts and accurate holes. Even slight wear can change the quality of the cut or even lead to improper material.
For this reason, many metal workshops employ drill bit sharpeners, especially electric or bench-mounted models, to maintain their bits. Regular sharpening not only prolongs the life of the bits but also enhances machining accuracy. Thus influencing the end product quality.
Just as in the metal industry, woodworking also requires sharp drill bits. Wood is a softer material and, therefore, does not require as much precision as metal drilling. However, sharp bits still are necessary to avoid chipping or splintering of the wood.
The electrical drill bit sharpener is popular because of the volume of work involved in large-scale commercial woodworking enterprises. They quickly sharpen large drill bits, and their bits are kept in optimal condition to minimize downtime.
Construction sites use drill bits to create holes in concrete, metal studs, and wooden framing. With varying materials in construction, bits can wear down quite quickly. Thus, carrying a manual sharpener on a construction site is very important to ensure that drill bits are always sharp.
As for large construction projects, they also provide their own drill bit sharpeners in order to prevent the bit from wasting away while time goes by. Since the cost of buying drill bits continuously will add up, it will be more economical to invest in a good bit sharpener.
Drill bit sharpeners are common in machining repair shops. Sharpened bits can be used again after they have been worn out. This is better and cheaper than buying new drill bits, which can also be expensive.
In this industry, both manual and electric sharpeners are used. The choice depends on the bit size and the bit's wear in general. Also, using a drill bit sharpener increases the bit's life span and reduces the amount of money needed to invest in new bits.
Grinding Angles
Drill bit sharpeners feature differing sharpening angles for drills. Most electric sharpeners have fixed angles for optimum performance. Manual sharpeners offer flexibility to satisfy various needs.
Grinding Wheels
Grinding wheels are fitted in the sharpeners. Electric sharpeners have more grinding wheels than manual ones. This is for sharpening bits of varying sizes. Diamond wheels are also included for heavy-duty use.
Bit Size Compatibility
All drill sharpeners vary in sharpening drill bit sizes. Small handheld devices are meant for small bits only. While large electric sharpeners handle any size bit as well.
Power Source
Handheld sharpener tends to be more manual, while electric ones are more electricity-based due to power sources. Constructing companies favor portable battery-operated sharpener for use on-site. In comparison, workshops favor electric sharpened because of consistent sharpening and time.
Understanding the use of a drill bit sharpener is very important. So, the article will provide details such as the use of manual sharpeners, electric sharpener usage, and some time being required at the vertical bench mounted sharpener. Here are the important usage scenarios for drill sharpeners:
Using a manual sharpener is simple. First, locate the appropriate slot according to the angle of the bit. Insert the bit and pull it through slowly. Ensure to apply even pressure to achieve an even edge. Do this for each flute.
For electric sharpeners, the process is a bit different. Most machines have preset angles and auto-feeding features. Place the bit in the designated slot, and the sharpener will automatically sharpen it. This is quite useful when bits have worn down considerably as it maintains the original factory angle.
Sharpening on a bench grinder requires more skill. The user must hold the bit at the correct angle while applying even pressure. It is recommended to use a fixture for consistency. This type of sharpening is usually reserved for high-volume operations due to its time demands.
For drill bit sharpeners' longevity, it is very important to maintain them. Below is a brief explanation of how to maintain different types of sharpener drill bits.
There should be considered the following quality and safety-related issues when selecting bit drill sharpeners. These considerations include component quality, period of usage, stability, and usage of personal-protective equipment.
The quality of the components directly affects the performance and lifespan of the drill sharpener. One must go for sharpeners with high-grade materials, e.g., sharpeners with diamond wheels or aluminum oxide wheels. These are better than any other material and will offer more resistance to wear and tear. Moreover, the motor should be powerful if it is an electric sharpener. This is especially important for heavy-duty tasks.
A prolonged operation can be treacherous for any machine. To ascertain longevity, opt for those with good ventilation or cooling features. Hence, in tasks requiring continuous use, periodical breaks are essential for cool-down. This prevents overheating and subsequent damage.
This is specifically important for bench-mounted and electric sharpeners. The unstable sharpener leads to uneven sharpening, which can make drill bits quite useless. It is also recommended that the sharpener be anchored or weighted down to prevent unnecessary movements during use.
It is important for people working with sharpener drill bits to use PPEs, particularly goggles, gloves, and masks. Drill bits tend to produce intense sparks, and the sharpener can produce flying debris, which can injure an individual if the individual is not well protected. Further, one should always inspect the sharpener and bits for any defects before using them. Consequently, never exceed the sharpener's capacity to prevent failure or accidents.
A1: The main difference is in usage and efficiency. Manual ones are inexpensive and portable, while electrical ones are automatic, accurate, and time-saving but costly.
A2: If an individual frequently uses the drill bits and would like to be able to drill sharp bits at any time, then a drill sharpener is worth it. Drill bits become blunt over time, and with a drill sharpener, one will always have sharp drill bits ready to use.
A3: The angle is important since it defines the cutting edge of the bit. This means that if the required angle is not there, even the sharpest bit won't cut well.
A4: Basically, it all depends on how often the drills are used. If they are used frequently, the bits should be sharpened after every use.
