Top 10 Die Grinders – Best of 2020 that Your Toolbox is Missing

Sometimes a decent piece of a die grinder is all we need to nail our grinding jobs, get our mountainous works done in a jiffy! A comfort grinder provides an edge-like experience with its perfected sanding, honing, polishing or machining job.  But raises the frown when comes the issue of the right amount of pressure. The confusion between whether you need a powerful motor or power-packed pressure, can relate? Happened to all of us in our earlier days.

Might not be that easy as it reads (Well… Things do sound simple as water while reading, Nah!). But never forget that there will always be ways for a little bit digging up (we mean research!) and unravelling the truth (or the proper product!)

Things to Consider – Before Buying a Die Grinder Worth of Money

If your visuals have grown tired reading till now (we really hope it’s not!), then we’ve some sorted things up to our sleeve for you. Here are a few lifesavers that the best die grinder worth of your hard-earned money should definitely possess.

I. POWER SYSTEM

AC-power grinders are plug-worthy into any common household – useful for a home mechanic or garage shop ones. On the contrary, DC-power grinders are plug-worthy from being directly hooked up to generators or welding machines – useful for professional mechanics.

Numerous modes of die grinders are also available on the marketplace. Cordless electric, corded electric, pneumatic angle, and many more. Based on personal preference and job site facilities, you should decide which kind of die grinder would suit you!

II. SIZE – THE BIGGER, THE BETTER?

Not necessarily! The bigger, the better, the stronger logic doesn’t necessarily apply here. In fact, a lot of pneumatic die grinders with bead-breaking force are just of normal size – neither too small nor too big. And also, most of the popular models out there in the market are of this same normal size.

When it comes to industrial project sites, you may find the more giant, more powerful die grinders as an apt choice for nailing the job!

On the contrary, when it is about mending some residential objects, you may find the pencil die grinders or pen die grinders as better feasibility. Due to their small precise construction, it is easier to nail tricky angles or compact spaces which bigger grinders fail to provide. Though these pencil grinders have lesser RPM force, it’s been made this way because – with the possibly best pencil die grinder, you will gain more controlling power over the precision job.

III. SPEED CONTROL – VARIABILITY or, FIXED?

Before you purchase a die grinder, better you find out what kind of texture you would be working against! For instance, wooden boards make a softer texture compared to other metals. [Normal die grinders usually works at full speed] So you need your grinder to go a bit slower on a wood board. And this can be made possible only if your grinder has variable speed control installed in its construction.

In essence, if you plan to use your grinder only for one-time, one type of job (where the working surface is pre-determined) – then you certainly don’t need variable speed control. You can opt for a fixed speed one!

But if you want to use that grinder for a long-term and different purpose, then better you purchase one with variable speed control.

IV. MOTOR – POWER & PROTECTION

Dust, heat and debris can affect the internal construction of die grinder and may even succeed in destroying it. And heat generation is usual because any machine will generate heat while operating! What we need for long-terminal maintenance is HEAT-RESISTANCE power of the motor. 

Newer models are being introduced at present times to safeguard the motor from unwanted dust and debris. These versions of grinder include sometimes motor guard or, automatic shutoff circuit. Motor guard prevents dust particles from getting into inside the mega motor!  And automatic shutoff system stops the over-heating issue from causing major damage to the motor… [Protections had never been easier, Nah!]

V. COLLET ANGLE – RIGHT ANGLE or, STRAIGHT HEAD?

One of the first things that come to anyone’s mind while shopping a die grinder is whether to buy a right-angle one or, straight-headed!

Straight or Linear Die Grinder: Portable, hand-held as opposite to bench grinders. With wheels on them, can work on larger pieces. Straight grinders can even be attached to small saws and cut hard into hard metals. Gives you a comfortable grip and convenient control in smaller spaces.

Right-Angle Die Grinder: Also portable, hand-held and opposite construction to bench grinders. Comes in great handy while operating in circular motions. Popular for accessing tough-to-reach spots, these right-angle grinders are specifically used on metal construction projects.

Frequently Asked Questions (FAQ)

All about the Perfect DIE GRINDER (PNEUMATIC & ELECTRIC)

What is a die grinder used for?

A powerful machine as die grinder can be used for multi-layered purposes. The list starts with grinding including bonded abrasive stones or mounted stones, grinding points, sanding with coated abrasive or expanding rubber mandrel. The grinder can also be applicable for machining on endmill, honing with fine-grit mounting points, polishing with fibre drum and polishing compound. Not to skip from the list, a die grinder laps with lapping compound and embeds a mounted lap to it.

What is the difference between a straight die grinder and an angle grinder?

Angle and straight grinders are varying forms of die grinders. You can differentiate them by their size, power, tool and appearance.

The principal distinction comes in for the purposes they are used. A straight die grinder is basically a rotary tool on precision work. On the other hand, an angle grinder can be used on rough grinding and cutting jobs.

Die grinders make an apt choice for die making jobs obviously! And to add with that, etching and engraving glass or metal or wood. Most importantly, makes fine precise cuts and grinds into the job!

90° Angle grinders make a better choice for rough grinding jobs. It can remove rust, and also sometimes mortar. Masonry, tiles and rebar cutting are one of its specialization.

How much of HP does a plunge router need?

Routers come in several motor size classifications.

  • Palm routers – considered ideal for trimming, hinge mortising, edge forming, slot cutting, small-scale dovetailing, window cutouts and decorative inlays – are typically within 1 Horse Power (HP) or even less
  • Mid-Sized routers – considered ideal for plus large-scale dovetailing, panel cutting, template design work and circle cutting – are typically available within the range from 1.5 HP to 2.25 HP
  • Full-Sized routers – considered ideal for router table or CNC corporation – are typically available within the range from 3 HP to 3.25 HP
Do I need to check for CFM and PSI Ratings in electric grinder?

Certainly not! PSI and CFM are only measures used in the Pneumatic die grinders. And so you should be the least bothered about those settings in your electric grinder!

PSI denotes the discharging pressure of air in a pneumatic grinder. And CFM expresses the Cubic Feet Meter, associated with the PSI amount.

How much power does an electric grinder need?

Easy question, not so easy answer… Is the most powerful one always the best man? Probably not always…

In a case involving tricky space, tough-to-reach spots – you’re going to need some grinder with swift control over.

In the case involving small jobs – lightweight, less powered grinders should do the trick!

On an average estimation, angled die grinders have a powerful 1.5-5 HP motor inbuilt. And straight die grinders tend to have smaller 0.5 HP motor, suited to their precision job.

What type of cutters can I use with a grinder?

Different kinds of cutters on market are available for die grinding use. On instance,

  • Grinding bits
  • Grindstone bits
  • Drill bits (small)
  • Milling cutters (small)
  • Disc-shaped saw blades (small)
  • Sanding drums (small)
  • Carbide burrs (small/ medium)
  • Sanding flap wheels (small)
  • Fiber wheels (small)
  • Wire wheels
  • Metal cutting wheels
  • Wood cutting wheels
  • Mounted laps

Care & Maintenance: How to Best Use a Die Grinder in the Safest Way Possible

  • Wearing Ear Plugs – for noise limitation
  • Using Full Work Gloves – for skin protection
