Bosch Power Tool Insider Guide: Decoding Bosch Power Tools Names/Model

Decoding Bosch Power Tools Names/Models

Ever wonder what GBH 2-23 RE or GSB 21-2 RCT stands for?

Did you know that Bosch product codes each have their meaning and interpretation?

Knowing them will aid you in your Bosch product selection process catered to your specific needs!

All Bosch power tools have their own unique model code devised by an alphanumerical system, understanding them can save you lots of time and money in getting the right tool that will deliver and do the job.

Let us now learn more about the names and models; the focus is on professional tools.

Example Model: G BH 2-23 RE

                        1

The alphabet above 1 categorizes the tool according to the functional area.

G represents that this product is a professional tool meant for industrial tradesmen and end consumer use.

All professional Bosch power tools are predominantly dark blue in colour.

2 other alphabets to denote the functional area are

P: DIY tools for DIYers, dark green in colour; and A: Outdoor tools or Garden tools, light green in colour.

DIY tools are more commonly used in the Europe and US markets where the materials dealt with are generally softer in nature.

Example Model: G BH 2-23 RE

                            2

The alphabets above 2 always consist of 2 letters. It defines the type of tools.

BH represents that this product is a Rotary Hammer.

Below is a list of types of tools:

BM = Drill

SH = Demolition Hammer

DM = Diamond Wheel Cutter

SB = Impact Drill

GS = Straight Grinder

ST = Jigsaw

SR = Screwdriver

WS = Angle Grinder

SA = Sabre Saw

DS = Impact Wrench

RW = Paint Stirrer

KS = Circular Saw

DR = Impact Driver

SM = Bench Grinder

CO = Cut Off Saw

OP = Multi-Cutter

SC = Shear

CM = Mitre Saw

BH = Rotary Hammer

NA = Nibbler

TM = Combination Saw

SG = Foam Cutter

SS = Orbital Sander

BS = Belt Sander

MR = Mini Router

KP = Glue Gun

HO = Planer

EX = Eccentric Sander

BL = Blower

HG = Hot Air Gun

AS = Vacuum Cleaner

Example Model: G BH 2-23 RE

                                    3

The numbers above 3 represents the crucial technical data partly abbreviated.

Different products have different crucial technical data, more commonly used ones are, weight of hammer (for rotary hammers), maximum concrete drilling (for most drills), power input in Watts, W; and battery voltage in Volts, V and Amperes, A.

As this is a rotary hammer, 2 represent a 2KG hammer. 23 represent 23mm maximum concrete drilling diameter. Note that the maximum drilling diameter differs between materials such as concrete, wood and steel.

Example Model: G BH 2-23 RE

                                        4

Last but not least, the letters above 4 designate specific characteristics, special feature and function of the tool.

The letters are meant to be interpreted separately.

R represents the function of Reverse Rotation. Reverse rotation meant that the tool is capable of rotating in a reverse direction ideal for screw driving.

E represents the feature of Electronic Control. Electronic control allows for a 2 speed control of the rotary hammer, High and Low. The variable speed control is essential for the purpose of screw driving; lower speed will give users better control of the tool for screw driving. The letters can have different meanings depending on the type of tool. Below is a list of letters and their meanings:

A = Dust Collection

B = Bow Handle

C = Constant Electronic

D = Rotation Stop

E = Electronic Control

F = Quick Change Chuck, Finder

I = Intelligent Tool

L = Long Shaft

P = Pendulum Action

R = Reverse Rotation

S = SDS System

T = Torque Control

V= Voltage, Vertical, View

X = Hexagonal Shank

In totality, GBH 2-23 RE can be interpreted as “Professional rotary hammer, 2kg, 23mm maximum drilling diameter capable to doing reverse rotation with variable speed control”

Another example, Model: GSB 21-2 RCT

• G: Professional tool
• SB: Impact Drill
• 21: Maximum concrete diameter i.e. 21mm
• -2: 2 Speed control (high & low)
• R: Reverse Rotation
• C: Constant electronic booster (help boost the speed of drilling despite strong pressure against the wall which will slow down drilling)
• T: Torque control system function

Finishing Versus Orbital Sander (from Amateur Woodworker)

Approximate Cost

Finishing Sanders: from S$44
Random Orbit Sanders: from S$119.90

Description

Finishing sanders come in two main types: block sanders and random orbit. Although either tools can be used as a finishing sander, they excel at different applications. Random orbit sanders are better for sanding large areas quickly. However, finishing/block sanders provide a better finish while also have the obvious advantage of being able to get closer into the corner as they do not have a circular base like orbital sanders.
Further, block sanders can use standard sandpaper that you cut down to shape, while random orbit sanders need specific circular sheets and this can make the running cost higher. If you only have the money for one of these sanders, we recommend a block/finishing sander. While it will take longer to get a good finish, the end result will be far better.
When purchasing a sander consider the following:

• How rapidly does the sander vibrate. This measurement is often in orbits per minute (OPM). The faster it vibrates, the quicker it will sand.
  
• Some sanders offer a variable speed option and this is worth considering as long as the price differential is low.
  
• Do not be overly concerned about the dust collection system. Many of these do not work very well anyway.
  
• If you do want a dust collection system, ensure that your sander comes with a hole punch system so that you can easily punch dust holes in standard sandpaper, rather than having to buy special paper (this only applies to block sanders -- orbital sanders require special paper anyway).
  

Using the sander

The normal weight of the sander is sufficient to sand and there is no need to exert extra pressure. Contrary to popular belief, additional pressure is detrimental to efficient sanding as it slows the speed of the pad.
Finishing sanders cause thousands of small abrasive grits to move in circular obits against the wood at a high speed. Each grain moves in the same direction, ensuring that the cutting action is uniform over the whole area. You should try to cover each part of the wood from many different directions to ensure that you get an even finish that does not have a bias towards movement in one particular direction.
Begin the sanding process with a relatively coarse paper (the coarseness will depend on how much sanding there is to do) and then move down to finer paper. Do not go from a coarse paper straight to a fine one, but step through the various grades. Too great a step will mean that you cannot sand out the "swirls" caused by the coarser paper.
Successful sanding is a result of patience and perseverance. The more time you spend on this step, the happier you will be with the final result.
