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.   Spade Drills are a known device which surpasses twist drills in many ways.   Operational :   More inherent Rigidity. Heavier feed rates compensates for the 10% to 15% reduction in RPM. More chip clearance adds to production efficiency. Quality of holes made by Spade Drills is Superior to the twist Drills. Hence Reaming/burnishing can follow immediately. Fractional sizes i.e. 25.1, 30.9 etc can be made available by making such blades.       Economical :   Two piece construction facilitate a number of blades on one shank. Blades are replaceable and can be reground. Same blades can be used on short, long and extra long shanks. Depth to diameter ration in Spade Drilling has been achieved upto 20:1 through Coolant arrangement is a must. With special Blades, core drilling, counter Boring and Bottoming to flat or contoured shape can be achieved. The shanks can be offered in straight to tapered, long to extra long and with ISO-40. We can give Spade Drills from 18.00mm to 140.00mm in 14 sizes.       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.

    We are pleased to introduce Mikron tool. They manufacture Solid Carbide Deep hole drills which are best in the world these tools are highly suitable for machining Titanium/Stainless steels /Deep hole drilling with through coolant drills upto L/D 30.       They make drills  for below typical applications   - Cross hole drilling - Deep holes with through coolant - Solid carbide Slitting cutters for automotive application as well as aerospace etc . - Deburring ,Chamfering (front and back) endmills for difficult to reach edges /spaces. - Micro-Endmills . - Carbide Slitting cutters

Jigs & Fixtures for VMC & HMC. These fixtures are made of good quality raw material and are quality checked, tested for ruggedness before handing over to clients within the specified timeframe. These fixtures are made designed as per customers component drawings.

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. BOBAR’s have been provided enough chip clearance space between blades and the two guide pads. Copious coolant supply will also prevent chips affecting the results.     Highlights   Blade with appropriate cutting edge geometry. The guide pads are positioned to absorb and utilize the radial and tangential force. Hence, overall effect is an efficient material removal and size-control of the bore. Axial parallelism and ovality is within 1 to 3 µm and is maintained over the entire bore length. Same accuracy is obtained in broken and interrupted bores with extended guide pads. Minimum surface irregularity is achieved by providing 3⁰ finishing lead angle on blades. Guide pads while controlling the cutting edge, burnish the whole surface by exerting a counter force to the cutting action. The only wearing part in ‘BOBAR’ is the Blade. This blade can be used from the both sides, Resharpened & Replaced. The guide pads require a constant lubricant film for longer life. Any commercial coolant emulsion (1:9 mixtures) serves the purpose. Stock removal: ‘BOBAR’ reams in a straight line and does not follow the pre-machined bore. For good all round finish, stock removal should be 0.15mm i.e.0.3mm on dia. Cutting speed: standard speed 12-25m/min, (Surface speed). Trials with different RPM, feed and rake angle of the blade should be carried out for achieving required finish, accuracy and production. The adjustment is only within the tolerance. The range given is to inform the Morse-Taper and reaming length available.
