Dormer Tools produce a range of Reamers to finish holes to H7 tolerance. Reaming has always been considered a finishing process and drilling a roughing process. Today, however, many tolerances that used to need a reaming process, can now be met by high-tech drills, such as in the CDX and ADX ranges.
Reamers only cut on the bevel and taper leads; the lands on the body do not cut. They are normally designed with an uneven pitch and an even number of teeth to prevent chatter and ensure good hole surface finish and roundness. They include Hand, Chucking and Machine Reamers with straight or Morse taper shanks. They are available in different materials, including carbide which offers the greatest resistance to wear. Carbide reamers are successfully used to cut steels on rigid machine set ups, but often, High Speed Steel designs will be more cost effective.

Landis Reamer Program
Landis Reamers for reaming, chamfering, and facing come in four basic styles - solid, detachable blade, insert blade and composite. The style supplied will depend upon the operation to be performed and the type of Landis die head in which it will be used. They can be identified by a symbol number stamped or etched on one of the flutes of the solid and composite reamers and on each one of the blades of detachable and insert blade-type reamers. |

Today, however, many tolerances that used to need a reaming process, can now be met by high-tech drills, such as in the CDX and ADX ranges.
Most common Reamers have a left hand helix because the main application is in through holes requiring chips to be pushed forward. For blind holes, Reamers with straight flutes or right hand reamers are recommended. |

- Made from long-lasting M-7 tool steel.
- The left hand spiral, right hand cut design prevents chips
from drawing into cut.
- Choice reamer flute diameters, OD relief, and chamfer relief
are all ground between.
carbide lapped centers. This provides:
- Consistent margin widths
- Concentricity between chamfer and OD
- The capacity to resharpen between centers |

Hard Part Reaming:
- Reaming in hardened Steel and HSS up to 68 HRC.
- Replaces internal grinding with improved geometry and surface finish.
- Time savings of up to 90%.
- Straightens holes after hardening. |

Reaming
Kennametal capabilities are not finished in just drilling a hole. When high quality holes are needed, the KM multi-cut high performance Reaming program is the solution. All of the Reamers will be ground after ordering specific to the application regarding diameter and cutting material. There are three different systems available: RMA (Reamer Monobloc Adjustable), RCH (Reamer Cutting Head) and RMS (Reamer Monobloc Solid Carbide)
RCH Reaming System
Flexible reaming system
RMA Reaming System
High performance reaming system.
RMS Reaming System
Unique cutting geometry and coating. |

CoroPlex™ MT
By introducing the multifunctional CoroPlex™ MT Sandvik Coromant establishes a new standard that is of outmost user benefit for operations performed with the latest of machine tool technologies.
CoroPlex MT is a combination of two winning concepts in one – CoroMill 390 and CoroTurn 107. It is either applied rotating as an effective tool for milling applications – or indexed in a number of optional positions for stationary turning using two different CoroTurn 107 inserts.
Sandvik Coromant´s multifunctional tool CoroPlex MT is designed for practically unrestricted use of all the insert positions possible without support of any extra software. Although CoroPlex MT is dedicated for Multi-Task machining it is easy to use the tool in somewhat older machines working with the software capacity limited to conventional standard cycles.
CoroPlex™ MT is an innovative multifunctional tool for finishing the workpieces in a single set-up with reduced downtime on the machine. It also completes together with CoroPlex TT twin tools, with two inserts in one holder giving the possibility to change operations momentarily, and CoroPlex SL mini-turret, with four turning tools in one, the dedicated tooling Sandvik Coromant provides Multi-Task machining. |

ZX Modular Boring Tools (MBT) offer versatility and economy when machining bores, counter-bores, tapers, threads, and complex contours inside components, over a wide range of diameters. These tools offer the highest cutting speeds and material removal rates available.
The MBT series is available in single-slide (MBT-S) and twin-slide (MBT-T) versions. All MBT tools feature 2:1 actuation ratio for easy programming. |
|
| A boring tool is usually a modular tool, consisting of a basic holder, adapter and a cutting unit in the form of a cartridge, slide or fine boring unit. A fine boring head holds a boring bar or cartridge. A reamer has a tool shank and a close pitch head with brazed blades. The tools, except the reamer, are radially adjustable within a specific diameter range. |
|
Designed with a length to diameter ratio of approximately 4-1/2 to 1 , this line of carbide boring tools features set-screw flats that position the cutting edge on exact centerline when used in a Criterion Boring Head.
They are available in two all-purpose grades of carbide - the ABT tools are a grade C-2 and are used on cast iron and all non-ferrous materials. The SBT tools are a grade C-6 and are intended for use on steel and other continuous chip materials. For the correct grade for your particular job we suggest you contact your carbide supplier or you may refer to the comparison charts found in most carbide catalogs.
Carbide Boring Tools with minimum boring diameters of 1/8, 3/16 and 1/4 feature a solid carbide neck and head. |

Sandvik Coromant now introduces CoroBore 820, a unique addition to its boring tool programme.
CoroBore 820 is a new solution for high productive boring preferably in roughing operations. The boring range is 35 - 260 mm and the boring depth is up to 4 x diameter. It is designed for internal coolant supply.
Three cutting edges allow a higher penetration rate with maintained tool life. A comprehensive programme of tool bodies, slides, shims and cutting inserts allow CoroBore 820 to be configured to suit the widest possible range of applications.
CoroBore 820 in combination with Duobore makes a highly productive team for rough boring from Sandvik Coromant. |

BoreSTAR out-performs any other kit when it comes to range, rigidity, accuracy and repeatability.
The BoreSTART kit is fast and simple to use (no spacers or complicated set-ups) but is extremely rigid and accurate. It is dial adjustable in increments of 0.0001". Range is from .314" to 6.69" (8mm to 170mm)

When the greater length of a standard boring tool is more a hindrance than a help, Criterion offers this line of Stubby Boring Tools. Maximum rigidity is assured whether the tools are used in a boring head or in the cross-slide of a lathe.
Available in shank diameters of 1/2", 3/4" and 1", these husky tools are made in both HSS and carbide. Stubby Boring Tools may also be ordered with square shanks. |

WhizIn, another revolutionizing patented product developed by WhizCut, is designed to improve productivity of internal applications. It has been specially developed for small diameters in internal turning applications, and is unlike anything else on the market.
The WhizIn tool holder has the carbide bar mounted at an angle to achieve the maximum stability for a set diameter. By grinding away less from the base of the insert, the insert becomes more stable. Other benefits are less grinding time and grinding stress and that the coolant may go through the tool holder and spray directly on to the cutting zone. |
