What is the difference between drilling a hole using a pedestal drill compared to drilling on a metal turning lathe?
On a pedestal drill the workpiece is static and the drill is in a vertical position and rotates. On a lathe the workpiece rotates but not the drill, and the drill is in a horizontal position.
What is difference between reaming and drilling?
Drilling is a cutting process in which drill is used to make a hole. Drilling process usually creates rough surfaces. Therefore, reaming is done after drilling to make a good surface finish, without changing the chemical and physical properties of the material. In reaming, only 5% of the material is removed (rest is removed by drilling process done before).
What the importance of drilling center and guided drilling?
Drilling centre and guided drilling get your hole in precisely the correct place.
What is the difference between earthing boss and earthing lug and where to use?
An earthing boss and earthing lug are parts of a grounding connection. An earthing boss is in a casting that allows for the drilling and tapping of hole. A earthing lug is used to bond a wire to the ground.
What is center drilling?
It is the process of drilling a locating hole at the end of a shaft while machining between centres.
What is the difference between bore and drill?
Bored is a verb used to describe a feeling or state you are in. (He, she, we, they, I) Eg.: I have nothing to do, so I'm bored. Boring is an adjective used to describe a person, object or activity (it makes you feel bored). Eg.: This documentary is very boring
What is a homophone for boring?
A homophone for boring as in being uninterested would be boring, which means drilling a hole. In this case the spelling is the same, they sound the same but the meaning is different.
Difference between boring and counter boring?
Both process enlarges an existing holewith a difference that in boring,the existing hole is enlarged throughout its length. Whereas in counterbore.enlargement is done upto a certain depth so that,say a bolt can fit in.
Why is it best to use the right size drill and boring tools?
Most metals are initially drilled with a narrower drill, forming a pilot hole. Then the right size drill is used to complete the drilling of the hole by widening the pilot hole.
What is the homophone for drilling a hole?
The homophone for drilling a hole is "whole."
What is the difference between drilling a hole using a pedestal drill compared to drilling on a metal turning lathe?
On a pedestal drill the workpiece is static and the drill is in a vertical position and rotates. On a lathe the workpiece rotates but not the drill, and the drill is in a horizontal position.
What is the difference between self-tapping and self-drilling screws?
Self-tapping screws have a sharp tip that can cut its own threads into the material, while self-drilling screws have a drill bit tip that can create a hole before threading into the material.

What is the difference between self-drilling and self-tapping screws?
Self-drilling screws have a drill bit at the tip that can cut through materials, while self-tapping screws have a sharp thread that can tap into materials without the need for a pre-drilled hole.
What is deep hole drilling?
Deep hole drilling is a machining process used to create deep, narrow holes in various materials, typically exceeding 10 times the diameter of the hole. This technique employs specialized tools and methods, such as gun drilling or BTA (Boring and Trepanning Association) drilling, to ensure precision and efficiency in producing holes with high aspect ratios. Deep hole drilling is commonly used in industries like aerospace, automotive, and oil and gas for components such as engine cylinders, hydraulic parts, and cooling channels. The process requires careful management of cutting fluid and chip removal to maintain hole integrity and surface quality.
What has the author S J Kravits written?
S. J. Kravits has written: 'Accurate directional borehole drilling' -- subject(s): Directional drilling 'Comparison of rotary and in-hole motor techniques for drilling horizontal boreholes in coal' -- subject(s): Boring, Coalbed methane drainage, Mine ventilation
What the importance of drilling center and guided drilling?
Drilling centre and guided drilling get your hole in precisely the correct place.
