New machining techniques require new Tools, which in turn lead to new machining methods. This constant interaction is the driving force which ultimately leads to progress. It is this very factor that leads to continuous development of tools and machine tools. Numerical Control of machine tools represents a milestone in production methods. However the increase in operating speed now possible, together with higher precision and production automation, also places new demands on the tools. Burnishing One Blade Adjustable Reamer (BOBAR) manufactured by SUPER SURFACE TOOLS CO., MUMBAI, INDIA, may be a solution to these new requirements.
Since the beginning of cutting technology for fine machining of bores, the reaming method has proved indispensable. One of the main reasons lies in the broad spectrum of application for which this process can be used- on all machines with either rotating or stationary tools. The original HSS multi blade reamers were replaced by carbide Tipped blade reamers. Carbide tipped adjustable floating, pair of blades in a holder (SAMAR & KOYEMANN) gave fine finish. Now single blade reamers with clamped, precision adjustable blade and guide pads have put a step forward. The increasing use of NC-Controlled machines, particularly machining centers, have brought a further need for tool development which will allow new methods of increasing performance to full advantage. This need is now met by BOBAR manufactured by SUPER SURFACE TOOLS COMPANY, MUMBAI, INDIA.
The cutting process is by means of a precision adjustable, rigidly clamped blade. At least two guide pads placed on the circumference of the head provide support and guide. In automatic production, it is vital that the chips removed do not affect the results. BOBARs have been provided enough chip clearance space between blades and the two guide pads. Copious coolant supply will also prevent chips affecting the results.

| We have given SAMAR for holes that are accurate, fine finished and without ovality. These tools are serving you for last 3 to 4 decades. Now we have come-up with Spade Drill to replace costly Twist Drills. These, we found, are successful in long and deep drilling upto 20 times its size(i.e. dia.75 1250mm deep with thro coolant). Recently we have successfully demonstrated Dia. 73 x 1250mm length in BHEL. It was a Skoda horizontal boring machine. RPM 18 and feed 0.5mm.The time saved was more the 1/3 or the earlier tools. We, therefore, want you to know that any problem of deep drilling can be tackle with our Super Spade Drill. | |

| Instructions For Using Spade Drills | |
| Generally the speeds used for H.S.S. Spade Drills are in the low to medium ranges. Whenever , the Feed is high, depending upon the hardness of the material , the speed can be varied to avoid vibrations. If the blade experiences burning on periphery, then reduce speed. While using Carbide Spade Drills, it is advisable to predrill the work piece with a dia.10mm twist drill & then to use the Spade Drill. The carbide Spade Drills are to be used with high speeds & low Feeds as given in the Chart. However, if any vibrations are occurring, then the Feed has to be reduce in increments. |

| It covers a wide range of sizes within one reamer. | |
| It has replaceable tungsten carbide tipped cutting blades. | |
| It has a positive constant float through-out the range. | |
| The float is at the cutting end eliminating special floating tool holders. | |
| It is easy to set size in the machine itself. | |
| No special wrenches or tools are required for setting. | |
| Two-bladed construction, with diametrically opposed blades fully supported over the width of blades allows | |
| Greater coolant and chip passage | |
| Lower cutting pressure | |
| Cooler cutting permitting closer tolerance and finer finish of the bore. |
